Final Exam Review

Sampling error refers to the difference that exists between what is believed to be true about:

After assessing the strength of association between variables, researchers should:

All of the following are true about probability sampling methods EXCEPT:

A measure of dispersion that identifies the distance btw the highest value and the lowest is:

Statistical significance confirms if research findings have useful application in SW practice

Probability samples are advantageous to the researcher because​

Why would it be important to report the standard deviation in addition to reporting the mean?

The mode value for age in the analysis is 51 years of age. This indicates that:

A population is a group of people that the researcher is interested in generalizing about.

The standard deviation portrays how far away from the mean scores on average are located.

Measures of dispersion show:

A variable’s level of measurement influences the calculations that can be performed on it.

At what level of measurement is the variable number of future incidents of abuse?

At what level of measurement is the variable ethnicity?

This distribution is negatively skewed

Inferential statistics are useful for determining:

A researcher evaluates the effectiveness of an intervention. The effect size indicates that:

If statistical significance is reported as p <.05 it means that the probability that:

Cluster sampling is a useful sampling procedure for large populations geographically scattered.

Inferential statistics are used to generalize findings from a sample to a larger population.
