A researcher thinks that how often someone reports visiting a science museum in a year is different for people with children and people with at least one child. They get the following output: Group Statistics Std. Std. Error Respondent's children Visits to No children N 797 Mean 0.27 Deviation Mean 1.077 0.038 science museum 1 or more children 2062 1.65 4.997 0.969 Independent Samples Test Levene's Test for Equality of Variances t-test for Equality of Means F Visits to Equal 4.492 Sig. 0.034 t -1.231 df 2857 Sig. (2-tailed) 0.218 science museum variances assumed Equal -1.979 2067.380 0.048 variances not assumed 1. Write up the results of the t-test in full APA format. Remember, this means that you should include the following: - Are we assuming equal variances? Why or why not? - mean and standard deviation for each group - the t statistic - the df the observed p-value (remember, this will differ depending on if this is a one-tailed or two-tailed test) indicate what the significance test tells you.
