What is Quantitative Data
Numerical Data
What are the advantages to Quantitative Data?
- Easy to take an analyse as data in numbers so can easily be summarised via statistics
- Much more objective, no interpretation, no bias possible, high creditability
What are the disadvantages to Quantitative Data?
- may not convey participants precise thoughts/ explanation due to fixed & objective answers, therefore low validity as no explanation
- Oversimplification of human experiences to simple answers can be consdiered reductionist as it reduces human experiences to Quantities
What is Qualatitave Data?
Descriptive, explanatory data
What are the advantages to Qualitative Data?
- Representable of true human reasoning & complexities as dont reduce to numbers; a hollistic approach
- Provides detail due to free range to allow participant to explain themsevles verbally or in writing, therefore inc. vailidity
What are the disadvantages to Qualitative Data?
- Much harder to detect patterns in data due to large ammount of information gathered, so many words cannot be simplifed into a few numbers - techniques such as Thematic Analysis are required
- Completely subjective to researcher consequently lowering creditability
Describe Questionnaires
- When participants record their own individual answers to predetermined questions
- provided in written form to negative face to face bias/ demand characteristics + to maintain standardisation
What are the advantages to Questionnaires?
- can easily be repeated e.g. standardisation
- respondants more willing to reveal personal information due to confidentiality
- Self-report allows for true records of individuals’ opinions
What are the disadvantages to Questionnaires?
- People dont always tell the truth can be influenced due to social desirability
- Literacy dependancy and temporal investment
- Susceptible to situational influences e.g. if person hungy it may influence results
What are Closed Questions?
- Fixed response questions, a closed set of responses to choose from
- Commonly answers predetermined e.g. numerical or Yes/No = Closed Questions
What type of data do Closed Questions gather?
Qualititative Data
What are the advantages to Closed Questions?
- Easy to analyse due to data being numerical e.g. easy to make graphs/ averages
- Answers very objective so will be interpreted identically by any researcher
What are the disadvantages to Closed Questions?
- Doesnt allow for expression of reasoning for answers due to predetermined/ limited answers
- Oversimplification of human emotions, limiting responses, people may want to answer with an option/ opinion that isn’t present
What are Open Questions?
Invites participants to give their own individual answers
What type of data do Open Questions gather?
Qualitative Data
What are the advantages to Open Questions?
- Provides heavy detail due to freedom to express own opinion, can express what really think rather than being restricted
- Can provide answers to unexpected theories due to open answer pool, this has 0% chance of happening in closed Qs
What are the disadvantages to Open Questions?
- Much more difficult to draw conclusions due to wide range of answers
- Interpreting what others are inferring leads to subjectivity, lowering validity as each researcher may have differing view
Describe Ranked Scale Questions?
A type of closed question where respondants are asked an assessment of their view via placement on a ranked scale e.g. 1-5
Give two examples of types of Ranked Scale Questions + define them
- Likert Scales - options ranked from 1 - 5
- Semantic Differentials - scale that uses bipolar/ contrasting adjectives e.g. strong-weak, least likely- most likely
What are the advantages to Ranked Scale Questions?
- objective way to represent feelings and attitudes
- Produces quantitative data which is easily analysed e.g. graphs
What are the disadvantages to Ranked Scale Questions?
- Social desirability bias may lead to unjust results/ misleading data & overall a lower validity
- Participants may want to respond identically to all questions e.g. pressing middle rank in scale each time to be quick and get survey done quickly
Name all 5 sampling techniques
- random sampling
- stratified sampling
- opportunity sampling
- volunteer sampling
List things not to do on a questionnaire
- Make it too long, risking disengagement
- Having the researcher in close proximity
- Poorly designed Questions e.g. leading questions, ambiguous questions or repetitive questions
What are Leading Questions?
- Subtly influencing respondant to give certain asnwer via certain phrasings of questions or giving example answers e.g.
- Do you experience shaking ❎LEADING
- What do you experience ✅NOT LEADING
Describe Random Sampling
- When every member of population has equal chance of being selected for the sample
- can be done via picking names out of a hat or using random number generator
What are the advantages of Random Sampling?
- Unlikey sample would be biased as sample has no control over who is included
- All members of population have an equal chance of being chosen
What are the disadvantages of Random Sampling?
- Time consuming as have to get target pop then identify sample and then contact to ask if willing to take part
- Once selected participants may not want to actually take part which can turn sample bias
- Target population may not be represenative e.g. all caucasian
Describe Stratified Sampling
- Sample is proportional represenation of target population as the population is broken down into smaller groups e.g. gender/ age/ school house
- Sample is taken from subgroups of target population e.g. if 30% of target pop = male then 30% of sample should be male
