HOMEWORK: RELATIONSHIPS AND REGRESSION TEMPLATE
This assignment is worth a total of 60 points.
Content: point values vary but are indicated in the template and total 45 points.
Format: point values vary but are indicated in the template for 10 pts. The remaining 5
pts are for placing answers in the correctly designated spots within the template in a clear
and easy to read format (e.g., all fit within the visible screen on the page) and uploading it
in an approved format (word or PDF). Thus, the maximum is 15 points for format.
Research consistently shows that children are more likely to have behavior problems if they
have less support available in their family. A local developmental psychologist had 10 sets of
parents complete validated scales to measure family support and child behavior problems,
where higher numbers indicate more family support or behavioral problems. She wanted to
test whether her local community’s data are consistent with previous research (that
behavioral problems are related to less family support). The data appear below. Enter it into
SPSS to complete the first set of problems (#1-7). 29 pts content / 8 pts format

#1 What is the research hypothesis (not the null hypothesis – the research hypothesis). State
whether it is one or two-tailed, and justify your answer. 3 pts
For this specific study, the research hypothesis is that more behavioral problems are
associated with less family support.
This would be one-tailed since according to previous research, there is a negative
relationship between less family support and increased behavioral problems.
#2 Calculate the appropriate statistical test using SPSS. Copy / paste all relevant output in the
space provided, making sure it is all viewable. 5 pts

#3 Write a Results section for your findings. Include the type of statistical test and results of
the test (clearly stating whether results are significant or not), confidence interval, and
interpret the coefficient of determination. 5 pts content / 2 pts format
A Pearson’s r correlation was run between family support and behavioral problems, with
results showing that r = -.623, p = .027 (one-tailed), 95% CI [-1.00, -.108]. 38.81%
variability in family support is accounted for by its relation to behavioral problems. The
results are significant as seen by the p – value of .027 which is less than alpha (0.05).
#4 Regardless of the statistical results above, use SPSS to calculate a regression analysis to see
if family support can predict behavioral problems. (Note this statement tells you what the
predictor (IV) and what you want to predict (the DV) is in this analysis). Copy / paste all SPSS
output as images in the space below. 5 pts
