Nonprobability samples are easier, cheaper, and faster to get. What is their main disadvantage that would force a researcher to do probability sampling?

Describe a specific marketing research situation when nonprobability sampling would be appropriate, despite this disadvantage.

What changes to the research problem would change your approach from a nonprobability sample to a probability sample?

#### Solution Preview

The main disadvantage that would force a researcher to do probability sampling is that they are expansive and require more time to complete. This is important because math can take time to complete, but there is always some level of error present because humans are not perfect. Regardless, doing a ...

## Understanding Research

Suppose you wish to measure the effect of physical exercise on self-esteem. What type of experimental design would be most appropriate? Describe the types of groups necessary for this design. How would you measure your variables? Which threats to internal validity would you need to consider?

Almost daily, we hear about research that seems to contradict earlier findings. One day, for example, a particular food is good for you and the next it is not. What does this reflect about the scientific method? What are the advantages and disadvantages of the scientific method?

Hypothesis 1: It is hypothesized that soccer coaches of younger, coed teams, treat males and females on their teams differently. More specifically it is hypothesized that on coed teams the boys are kept in the game longer periods of time and are more likely to play offensive positions while girls are more likely to be on the sidelines and to play defensive positions.

Hypothesis 2: It is hypothesized that age is related to attitude toward violence on television. More specifically, it is hypothesized that people in their 40s and 50s are more critical of TV violence than are people in their 20s and 30s.

Hypothesis 3: It is hypothesized that residential mobility affects academic achievement. Specifically, it is hypothesized that children from families that have lived in no more than two different communities during their elementary school years tend to have higher academic achievement than do children from families that have lived in three or more communities (Adler and Clark, 1999).

b. For each variable in each hypothesis, what method(s) of data collection would you use? Suggest a way to measure each of the variables.

What are the key differences between probability and non-probability sampling designs? Identify and briefly discuss the major types of probability sampling. Although convenience samples are widely used in research, what undermines their claims to generalizability?

What is the role of statistics in social science research? Be sure to distinguish between descriptive and inferential statistics.
