Determine the following descriptive statistics. In order to do so, Click Descriptives, drag Mischief to variables and Cloak to the split option. This provides you with descriptives for those labeled 0 (no cloak) and 1 (cloak).

No Invisibility Cloak Invisibility Cloak

N = _________ n = ________

Mean = _________ acts Mean = _________ acts

s = _________ acts s = _________ acts

Ignore the independent samples test provided automatically when you open the data set and instead run a single sample t-test on the Mischief variable to determine at a = 0.05, is there a significant difference in acts committed while wearing an invisibility cloak compared to the general population.

(Click the pull down arrow next to T-Test One Sample T-Test Select Mischief from the variable list and drag or click to arrow to place it in the test column on the right)

*Please also select the additional statistic of Effect Size and ensure that you are using the correct null hypothesis (is this one-tailed or two, directional or non-directional?)

Write the results of this analysis in APA format: ____________________________________________
