Create two histograms and provide interpretations. Calculate measures of central tendency and dispersion and provide interpretations. Submit your assignment as a Word document, beginning with a properly formatted APA title page. Include a reference list if necessary.

On page 2, start Section 1. Write your report in narrative format, integrating your SPSS output charts and tables with your responses to the specific requirements.

Below each histogram, provide an interpretation based on visual inspection, using the following terms: skew, kurtosis, outlier, symmetry, modality. Comment on any differences between males and females regarding their total scores. Analyze the strengths and limitations of visually interpreting histograms.

Section 2: Measures of Central Tendency and Dispersion

Compute descriptive statistics, including mean, standard deviation, skewness, and kurtosis, for the variables: id, gender, ethnicity, gpa, quiz3, total. Paste the descriptives output into your Word document. Below the table, indicate which variables are meaningless to interpret for these statistics and justify your decision.
