Quantitative Research: Planning and collecting (S6)

Question 1

What are the Quantitative (Descriptive) Research Methods

Answer 1

• Formulate the objectives
• Create a sample structure
• Prepare the research instrument (survey)
• Collect the data
• Analyze the results (SPSS)

Question 2

Sampling Procedure: Define the Target population

Answer 2

• Define the population through sex, age, origin, location, etc.

Question 3

Sample Procedure: Identyfing the Sampling Frame

Answer 3

• The sample selected has to be representative of the population
• The information gathered from the sample needs to be generalizable for the population
• This is a Database where we will go get a sample to represent our population

Question 4

Sampling Procedure: Select a Sampling Frame

Answer 4

• Probability (known, non-zero chance, not necessarily equal of being selected): This is when we have access to a sampling frame that already exists
• Non-probability (unknown): no sampling frame exists

Question 5

What are the different technique of Probability sampling

Answer 5

• Simple Random: You select a random amount of people from your list
• Stratified: Divide the population in groups with specific characteristics and select people from each groups
• Cluster: Divide the population into groups which include all the different characteristics, and select one single group to analyze

Question 6

Non probability sampling: what is Convenience sampling

Answer 6

• You use the people at your disposal (It’s Convenient)
• Respondents who fit the target you are looking for
• This Sampling technique is less good as you ask people who are not representative of the population

Question 7

Non probability sampling: what is Judgement sampling

Answer 7

• You Judge as a researcher that one person (Group) is better to answer the survey than others. (Mostly used in B2B research)

Question 8

Non probability sampling: what is Snowballing sampling

Answer 8

• You interview one person that matches your target segment and that person refers you to other people they know that fit the target to interview them. This process repeats itself so on and so on.

Question 9

Non probability sampling: what is Quota sampling

Answer 9

• In Quota sampling you ask the people that represent your sampling characteristics (target segment) until you reach your mark for each representation required.
  -This is the best option for non probability sampling

Question 10

What are the Types of errors

Answer 10

• Sampling error: Discrepancy between statistical and true value of population
• Non-sampling error: Due to errors in conception, logic, interpretation of responses, statistics, tabulation, etc.

Question 11

What is a Nominal Measurement scale?

Answer 11

• A nominal question is a single answer question that is a qualitative question
• Ex Gender: Male, Female, Non-binary, Prefer not to say

Question 12

What is a Scale Measurement scale?

Answer 12

• Answers fall on a scale like what is your age: 18,19,20,21,22
• The answers provide quantitative data
• usually they have a measurment scale like “1 is I don’t like it”, “5 is I like this very much”

Question 13

What is a Ordinal Measurement scale?

Answer 13

• An ordinal measurement scale is a type of scale used to rank or order items according to some characteristic, but without assuming equal spacing between the ranks.
