“Conducting Experiments for Gaining Customer Insights aka data marketing experiments

Question 1

casual conclusion

Answer 1

how one factor caused a change in another variable of interest

Question 2

casual research

Answer 2

aka experiments
allows a firm to make cause and effect statement

Question 3

cause and effect stamenent

Answer 3

can be made if it can be shown with a high level of internal validity that the casual variable or indepedent variable was responsible for the change in the outcome variable or dependent variable

Question 4

objective of experimental design

Answer 4

to create groups of respondents in a way that observed changes in one group can only be attributed to the casual variable
done through experimental design

The main goal of experimental design is to figure out if one thing (the cause) is really affecting something else (the effect). To do this, we create different groups of people (respondents) and treat them differently in a way that we can clearly see if the changes in one group are caused by the factor we’re testing

Question 5

experimental design

Answer 5

carefully gather data and then evaluates it to draw conclusions then do statistical analysis
when looking at causality, use a control and trewtaenet group
in the treatment group you vary the casual factor aka the indepedent factor
then observe the level of dependent variable

Question 7

three conditions allow us to infer casualty

Answer 7

1. if the two groups are equivalent in all other respects minus what u are testing
2. of there is a stisatical association
3. we can rule out other possible explanations for the observed association
   if yes we can conclude that the independent variable causes a change in the dependent variable

Question 8

customer focused experiments should balance two types of validity

Answer 8

internal validity and external

Question 9

internal validity

Answer 9

an experiments ability to unambiguously show a cause and effect relationship –> the extent to which we can attribute the change in dependent variable to the indepdent variable and not to other factor

Question 10

major concern for internal validity

Answer 10

have to ensure that the treatment group and control group are equal
achieved through random assignment or matched samples

Question 11

random assignment

Answer 11

occurs when each experimental unit (ex: each salesperson) is randomly assigned for inclusion in the control and treatment group
each salesperson has an equally likely chance of being assigned to either the treatment or control group
statistically compare each group
use this but if not possible, use matched samples

Question 12

if treatment and control are unequal

Answer 12

we have selection bias – when the treatment group is chosen using a methodology that precludes random assignment
random assignment is not always feasible however

Question 13

matched sample

Answer 13

as a technique for generating a control group is used when legal, ethical and practical consideration preclude random assignment

Question 14

external validity

Answer 14

the extent to which results of the experiment can be generalized or extrasploted to oder people, settings and time
do the results from one experiment with high internal validity apply to other situations
differences in setting can limit external validity

Question 15

systemTIC BAISES

Answer 15

can threaten the random assignment protocol

Question 16

threats to internal validity

Answer 16

1. history–> any variable or events other than the ones in the xperiemnet that affect the value of the Fdepdenet variable

Events or variables outside the experiment that affect the dependent variable during the course of the experiment.
Example: If you’re testing the effect of a new advertisement on sales, but during the experiment, a major economic event (like a sudden price increase for competitors) occurs, this could influence the sales, making it hard to tell if the ad itself caused the sales changes

2. maturation–> any economic, biological or psychological processes that systematical vary with passage of time

Changes within participants over time that are not due to the experimental treatment but to natural processes (e.g., aging, learning, fatigue).
Example: In a long-term study on the impact of a new training program, employees might improve over time due to gaining experience or becoming more familiar with their tasks, not because of the training itself

3. instrument varaiton–> a change in the measuring instrument t
4. experimental unti moratloty–> differential loss of respondents from dif groups
5. pre messuremnet/ interactive testing-
6. selection bias
7. statically regression –> special type of selection bias
8. enchahing effect of selection bias –> non random assignment

Question 17

external validity threats

Answer 17

1. surrogate situation–> when the expeiemtal task is so contrived that it is unlikely to be a reasonable proxy of the reality that the researcher wants to study
2. measurement of dependent variable: whe deponent variable does not map on to the behaviour or construct of interest
3. meaduremtn timing- If the timing of measurements in the study is not optimal or does not align with when the effects would occur in the real world, the findings might lack relevance when applied outside the study.
4. sample selection –> sample may not be representative of the population

Question 18

internal vs external. which is more desirable?

Answer 18

internal is necessary for drawing casual conclusions so even if it has high external not good
customer focused firms should strive to optimize both
use high internal to draw conclusions but use external to go beyond the conlsisions
there is a trade off between external ad internal for single customer focused research studies

Question 19

pseudo (bad) designs for customer focused expriemets

Answer 19

many lack internal validity –. cant establish causality
1. one shot cause study –> lacks a control group that is equivalent to the treatment
2. one group pre/ post test design–> faulty pre post
3. static group comparison

• show that there is a need for a control group that is the same as the tatrement and best accomplished through rands assignment

Question 20

true (good) designs for customer focused exorieennts

Answer 20

1. post test only, control group design–> rather than creating the tatrement group based on judgement or cmveneimce, experimental units are randomly assigned to the treatment or control group
2. pre test/ post test control group design–> before, exposing he treatment group to the treatment, but after random asisgmemt, a pre measurement is taken on the deponent variable. serves as the baseline from which changes in the deponent variable can be evaluated
3. avdnavced casual experiments
4. time series or quasi experiments

Question 21

overall

Answer 21

1. establish two equivalent groups aka control and treatment , established through random assignment or if need be matching
2. researcher has to carefully evaluate the study and its context to asses threats to external and indternal. internal - high, casual inference can be made. external = low, care should be taken o project the results beyond the context of the current experiment
3. conducting the approbate statistical analysis should answer 3 questions: iOS the difference statistically sigfniacant, how large is the impact, os the impact pos or neg. we use ANOVA
4. researcher should assess the applicably of the results. just bc results are statistically significant may not mean they are relevant, useful of applicable

Question 22

three types of marketing research

Answer 22

exploratory, descriptive, casual
(eiley digs Chloe)

Question 23

exploratory

Answer 23

methods: case studies, focus groups
felxible, versatile , discobery of ideas and insights

Question 24

descriptive

Answer 24

surveys, panels
preplanned, structured, conclusive
describe market characteristics or functions

Question 25

casual

Answer 25

experiments manipulation and control of variables determine cause and effect relationships

Question 26

focus group example

Answer 26

New smart HDTV focus group May have a focus group where questions will be asked in an open ended manner Show a prototype tv in action Ask open ended questions: what do you think, like, dislike, change, questions Let participants speak freely Content analysis of focus groups discussion→ Content analysis” of focus group discussion => analysis in the form of words (not numbers) => e.g., verbatim statements made by particiipants (maybe frequency of mention can be a numerical output) Identify important features & other (emergent) issues not known to marketer yet Before spending a large budget on launching a compagne may want to show to focus group to ask their likes and dislikes Different book covers may be tested in focus group Look at focus group answers , show them something and ask them questions Goal: To understand participants' initial impressions, likes, dislikes, and suggested improvements regarding the new smart HDTV, as well as uncover any unknown needs or preferences. Participants: Select a sample of diverse consumers representing your target market, ensuring they can provide a range of perspectives. Prototype: Show a working prototype of the smart HDTV to the participants, allowing them to interact with it directly to experience its features.

Question 27

quantitive

Answer 27

Measured in numbers Two examples : customer satisfaction surveys (we want to actually measure customer satisfaction and benchmark it against competitors )

Question 28

Attribute Importance Survey - segmentation of customers

Answer 28

Can do surveys to understand how to position your brand to different segments What Are the important attributes in each segment Can do a survey and give a list of attributes to be ranked in order of importance

Question 29

experiment

Answer 29

A survey: has questions and numeral answers Only experiments can determine cause and effect cause and effect: very important concept, cause and effect is important because marketers want change something in the marketing mix (cause) the response is the effect For example, suppose a company adjusts its product pricing, ad campaign, or placement strategy (all parts of the marketing mix). In that case, they want to know if these changes directly lead to a desired outcome, like increased sales, more customer engagement, or higher brand loyalty

Question 30

If case and effect is so important, need to know that a certain cause leads to a certain effect Four conditions to be sure to establish a cause and effect relationship

Answer 30

1) association --> need correlation between cause and effect 2) temporal --> cause must happen before the effect ( If you’re testing whether an exercise program causes weight loss, the exercise program needs to start before the weight loss happens, not after) 3) eliminating other causes 4) mechanism between cause and effect (There should be a logical or plausible mechanism that explains how the cause leads to the effect. Without this mechanism, it’s harder to justify that the cause is directly responsible for the outcome.) ex: vaccines and immunity. the mechanism is that it increases the number of white blood cells alyson tries making eggs

Question 31

temporal

Answer 31

Have to administer the cause first and then do the effect later bc cause leads to effect Necessary but not sufficient bc next two are important Things that have colrreation and temporal precedence but arent cause and effect Ex: length of womens skirts based on fashion and stock market performance , there is a positive correlation between these 2, no underlying cause No cause but happens to be correlated Ex: correlation vs causality Dont conclude causality from temporal and association alone if a brand wants to claim that an ad campaign led to higher sales, the campaign has to run first, with sales increasing afterward. This sequencing—where the "cause" precedes the "effect"—is crucial but isn’t enough to establish causality by itself. correlation isnt causation: For instance, the length of women's skirts (a fashion trend) and stock market performance have shown a positive correlation in past studies, but it’s unlikely that one truly affects the other.

Question 32

eliminating other causes

Answer 32

important Apple day keeps the doctor away: apple is the cause, keeping the doctor away is the effect. You can ask a bunch of people if this is true. Does this mean eating apples leads to better health? Not necessarily, may be other hidden variables or background variables (maybe none of them smoke or just lead healthier lives, dont know the other causes) 1) control vs experimental 2) measure other causes and use covariates 3)list other causes and eliminate them POST TEST only control group

Question 33

how to rule out other causes

Question 34

Cause and effect in marketing: online experiment

Answer 34

If a certain add works better than another in an experiment, have to ask why? The logical reasons in marketing have to do with concepts→ our consumers are high effort, have attribute information they consider important, or my customers are low effort and respond well to heuristics (emotions) Why does washing your hands kill germs? soap breaks down germ cells Why did people keep believing this false cause and effect claim: authority norm, social proof, confirmation bias, correlation and temporal precedence Correlation and temporal precedence: did bloodletting and patient improved, but logically they would have improved anyway without the blood letting (confirmation bias will continue to tell people blood letting works) Cause and effect→ internal validity External validity→ generalizability You can genralize sometimes → three conditions to be met

Question 35

External Validity:

Answer 35

Ability to generalize cause→ effect to a broader population External validity refers to whether the cause adn effect relationship found in the experiment can be generalized tot he population in question (rather than only those who took part in the experiment) High external validity (generalizable) if using right sampling frame that covers entire population random sampling of experiment participants from the population Pick an adequate sample size ( 1000-2000) Need two randoms

Question 36

threats to external valdiidty

Answer 36

Surrogate situation ; Experiment is so unrealsotsic that you cannot be confident that the results will apply real world Measurement of dependent variable: This happens when the way you measure the dependent variable (the outcome you’re studying) doesn’t accurately reflect the real-world behavior or concept of interest) If you're measuring customer satisfaction by only asking one yes/no question, you might miss nuances in how customers really feel, which could lead to inaccurate conclusions about satisfactio Measurement timing; (The time at which the dependent variable is measured can impact results. If the measurement occurs too early or too late, the results may not accurately capture the true effect of the treatment. Example: If you're testing a new training program, measuring employee performance immediately after training might not show long-term effects. Conversely, waiting too long might allow other factors to influence performance) Sample selection ; (This refers to whether the sample of participants in the experiment represents the larger population you want to generalize to. If the sample is not representative, the findings may not apply broadly) Megan misses sams spit

Question 37

cause and effect/ internal validity

Answer 37

design experiments with these basic principles in mind - control group and experimental groups , random assignment of participants to conditions, measure dependent variable, measure poentntial covariates (measure the factors that could influence the outcome) - do both pre pot measurement only if no pre measurement bias - ensure cause comes before effect in time - ensure there is a mechanism between cause and effect = observe correlation between cause and effect - then go through list of threats to cause and effect (i.e internal validity ) and logically rule them out

Question 38

generalizability/ external validity

Answer 38

select participants with these basic principles in mind - randomly select participants from the population using right samplig frame and right sample size - then go trough the list of threats to geenralizatbikty (i.e external validity) and logically rule them out

Question 39

what to do/ ask in a focus group

Answer 39

let partipcnats speak freely show prototype ask open ended questions dont ask questions with numbers

Question 40

association and temporal precedence

Answer 40

not enough to etsbalis cause and effect

Question 41

pre test and post test vs just post test

Answer 41

Pre-Test and Post-Test Control Group (no anchoring bias) Design is ideal when you need to measure change over time and have more control over pre-existing group differences. accurate but may have anchoring bias Post-Test Only Control Group Design is simpler and avoids testing effects but requires careful randomization to ensure group equivalence. simpler and less accurate

Question 42

high external validity

Answer 42

- Using right sampling frame that covers entire population – Random sampling of experiment participants from the population – Pick an adequate sample size (1000-2000)
