To complete Part A
1. Exploratory Data Analysis.
a. Perform Exploratory Data Analysis on all variables in the data set. Because you are going to focus on Extroversion and Agreeableness, be sure to include scatterplots for these combinations of variables (Student Agreeableness/Lecture Agreeableness; Student Extroversion/Lecture Extroversion; Student Agreeableness/Lecture Extroversion; Student Extroversion/Lecture Agreeableness) and include the regression line within the chart.
b. Compose a one to two paragraph write up of the data.
c. Create an APA style table that presents descriptive statistics for the sample.
a)
For the variable Age
Case Processing Summary
Cases
Valid Missing Total
N Percent N Percent N Percent
Age 404 94.0% 26 6.0% 430 100.0%
Here we can see that there are 404 are valid observation and 26 are missing observation
Descriptives
Statistic Std. Error
Age Mean 19.60 .172
95% Confidence Interval for Mean Lower Bound 19.26
Upper Bound 19.94
5% Trimmed Mean 19.20
Median 19.00
Variance 11.888
Std. Deviation 3.448
Minimum 0
Maximum 43
Range 43
Interquartile Range 2
Skewness 2.350 .121
Kurtosis 17.989 .242
From the above analysis we see that the mean and median are approximately are equal but the difference are very small therefore we can say that the data distribution are approximately normal distribution. Also the data distribution are positively skewed and also leptokurtic.

Age .279 404 .000 .600 404 .000
a. Lilliefors Significance Correction
Data distribution test for normality is significant therefore the distribution of the data is normal.
From the above histogram of the data we can say that the data is leptokurtic.
From the above diagram we noticed that the data points lie around the straight line, from this point of view we can say that data distribution is normal.
From the above figure we observed there are some outliers and mean and median are lies very closely therefore the distribution is normal.

Interquartile Range 11.00
Skewness .005 .119
Kurtosis -.312 .238
Mean and median are approximately equal and data distribution is positively skewed and plateokurtic.
Tests of Normality

Statistic df Sig. Statistic df Sig.
Student Neuroticosm .042 420 .075 .993 420 .055
a. Lilliefors Significance Correction
The normality test for the data is not significant.
But from the q-q plot we can say that the data distribution are approximately normal.
Also from the histogram data distribution is normal distribution.
