Chi-Square
Note: Chi-square is used when you have nominal
variables or mixed variables such as nominal and scale or nominal and
ordinal. Cross-tabs is used for ordinal and scale variables.
Review the analysis in the output window.
In the first row of the table under “Chi-Square Tests,” for each variable, look
for “Pearson Chi-Square.” The value, degrees of freedom (df) and
significance (P-value) is listed. The next table for each variable lists
the frequency of occurrence.
Using the “example of how to write about your
results” on page 107 in SPSS for Introductory Statistics, write an
explanation of your results. You do not need to include the X2 or the df values or the last
two sentences about Phi in your write up. Use the directions in Appendix C for
creating an APA formatted table to go along with your write up.
Chi-Square Write Up Example
To investigate whether males and females differ on whether they
took algebra or not, a chi-square statistic was used. Assumptions were
checked and were met. Table 1 shows the Pearson chi-square results and
indicates that males and females do not differ significantly on whether or not
they have taken algebra (N=75, p=.065). Males and
females are both expected, under the null hypothesis, to take algebra in high
school.

Correlation
Review the analysis in the output window. The
first table provides the descriptive statistics which includes the mean (M),
standard deviation (SD) and total number of responses (N). The second
table is the correlation which includes the Pearson Correlation (r),
Significance (p) and total number of responses (N).
Using the “example of how to write about your
results” on page 128, chapter 8, in SPSS for Introductory Statistics,
write an explanation of your results. Use the directions in Appendix C for
creating an APA formatted table to go along with your write up.
Create a word document for the two analyses,
save the document and title it, “Correlation.” Submit this assignment to the
lab 3 assignment drop box.

Correlation
Write up Example
To investigate if there was a statistically significant
association between father’s level of education and SAT scores, a correlation
was computed. Father’s education was skewed which violated the assumption
of normality. Thus, the Spearman rho statistic was calculated, r =
.22, p = .067. The direction of the correlation was positive but not
statistically significant. This means there is no association between
students who have fathers with high education levels and SAT scores.
