Name two types of data that a qualitative researcher might collect. 

Interview transcripts, field notes, photographs, diagrams, audio recordings, diaries, official records, newspaper articles

100
Why is experimental research commonly referred to as the most powerful type of design. 
It can establish cause and effect.
100

What is the name for a group of people that the researcher is interested in knowing about ?


(Target) Population
100

This type of measurement scale identifies categorical differences among individuals


Nominal scales
100

What is the most common measure of dispersion of data?


Standard Deviation
200
What are two approaches to qualitative research?

Biographical Study

Case Study

Phenomenological Study

Grounded Theory Study

Ethnography


200
Which variable does the experimenter manipulate in an experimental study?
The independent variable. 
200
Under what conditions is a simple random sample most likely to be non-representative of the population?
You have a small sample (40 people or less)
200

This is a type of measurement scale in which the numbers indicate equal differences between segments on a continuum, and has no true zero point

Interval scale
200

How do you describe the distribution when most scores are clustered around the mean and there are relatively few extreme scores?


Normal distribution
300

Provide an example of a research question that can be answered qualitatively

Think in terms of exploring, gaining more in depth understanding (e.g. using how and why type questions).

300

The process in which every individual who is participating in an experiment has an equal chance of being assigned to any of the experimental or control conditions being compared

Random assignment
300

Name the sampling method in which a sample is obtained by selecting every nth name in the population


Systematic sampling
300

This type of reliability indicates that items within an instrument correlate with each other


Internal Consistency
300

How would you describe the distribution of the scores from Group A?

A: 1,1,2,9,9,9,9,10,10,11


Negatively Skewed
400
What is the most common type of sampling method for qualitative research?
Purposive
400

One limitation of experimental design is that it lack _________________, which is the extent to which the findings of a research study are able to be generalized to real-life settings.


External Validity
400

What is the main sampling type in which presumably every member of a population has an equal chance of being sampled ?


Random sampling 
400

This type of validity indicates that the content and format of the instrument are consistent with variable of interest


Content validity
400

What type of hypothesis is the following?


H0: µ1 = µ2


Null hypothesis: There is no difference between the means of each group. 
500

Qualitative researchers care about ___________, which is the natural setting as a direct source of data .


Context
500

What is the processes called in which, to increase the likelihood that groups of subjects will be equivalent, pairs of subjects may be matched on certain variables.

Random Assignment with Matching
500
Name the main reason that a researcher would do stratified random sampling. 

If they suspect that different groups (strata) may vary in their behaviors


500

This type of validity involves the relationship between scores on one instrument and an alternative instrument


Criterion Validity
500

Imagine that we determined that the probability of the research hypothesis (µ1 = µ2) being true is: p = .03 (3 out of 100) . 

What should we do with the null hypothesis?


Reject the null and retain the research hypothesis.
