The following data examine the relationship between two variables, the quality of marriage and
the quality of parent–child relationships. You can use SPSS or excel for this assignment or you
can work them out old fashion, by hand (show your work). Use the data to:
a. Classify the levels (measurement level e.g. nominal, ordinal, interval, etc.) of data
b. Calculate measures of central tendency (mean, median, and mode) and variability (range,
SD, and variance).
c. Write a null and research hypotheses for the variables.
d. Create normal and binomial curves/graphs or tests to show if the data is normally
distributed or not.
e. Run/Calculate and interpret confidence intervals for the data (You can use the t tests to
get the CI).
f. Run/Calculate and interpret statistical hypothesis testing for:
a. One sample (Mean) test
b. Two samples (independent t-test) test
c. Correlations (interpret these data using the general range of very weak to very
strong).
g. Determine if the null hypothesis can be rejected using alpha criteria.
