Solutions

Expert Solution

  • Assumptions of normality (Shapiro-Wilk)

The SPSS output is:

The assumptions of normality are met for arousal.

  • Homogeneity of variance (Lavene)

The SPSS output is:

The Homogeneity of variance can be assumed for this data.

  • Outliers

The SPSS output is:

There are no outliers in the data.

  • Skewness/Kurtosis

The data for sex is negatively skewed and positively skewed for film.

Kurtosis is the same for both factors.
