2nd Half Can You Questions Flashcards
Explain what a literature review is using research language
Is a review of the literature done before research is conducted to know what has and has not been done already and generate a refined research question or purpose.
Describe several unique pieces of info we would learn from conducting a lit review
The populations studied Measures that have been used Independent variables Procedures How the data was collected How results have been similar or different Any conclusions that have been formed
List 3 outcomes of a lit review
Found out what has and hasn’t been done
Narrow your research focus
Develop hypotheses
Develop methods
Random sampling “gold standard” why ?
Because it ensures that the sample represents the larger population
Difference between pure descriptive and survey research
Pure descriptive is different than survey because it is strictly taking objective measures and comparing them;whereas survey research allows for subjective data
Strength and weaknesses of pure descriptive
Strength - objective measures. No interpretation.
Weaknesses - increased costs in time money and energy. Increased participant burden and harder to get a large sample size
Strengths and weaknesses of survey research
Strengths - easier to obtain large samples and data can be gathered relatively quickly
Weaknesses - rely on self-reports and subjective data introduces bias. Response bias and recall bias
Response bias and recall bias. Examples too
Response bias is giving a desirable response that might not be completely truthful. Example: saying you consume more veggies and fruits because you know you should.
Recall bias: relying on memory and that there might be things forgotten. Example: how many times over the past 2 months have you exercised.
The difference between ordinal and ratio data
Ordinal data is that of a likert scale where we can infer that something is more or less of something else
Ratio data is more comparison in that something can be twice as better than something else
Compare and contrast the strengths and weaknesses between longitudinal and cross-sectional research
Longitudinal research takes a longer amount of time but has more validity because we evaluate individual changes.
Cross-sectional research can happen faster because we get people of different categories over time and compare them, but we must account for differences in people and assume they are similar because they are not the exact same person
Explain the difference between descriptive and inferential statistics
The main difference is generalizability. With descriptive statistics we usually obtain a convenient sample and then all findings can relate back to that sample. But with inferential statistics we take a population that we want to generalize to and then pull a sample from that, in turn we can generalize not only to the sample but also the population of we randomly selected them.
