check/attached/file 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. Tests of Normality Kolmogorov-Smirnova Shapiro-Wilk Statistic df Sig. Statistic df Sig. 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. For the variable Gender Case Processing Summary Cases Valid Missing Total N Percent N Percent N Percent Gender 424 98.6% 6 1.4% 430 100.0% There are 424 observed values and 6 missing values . Descriptives Statistic Std. Error Gender Mean .28 .022 95% Confidence Interval for Mean Lower Bound .23 Upper Bound .32 5% Trimmed Mean .25 Median .00 Variance .200 Std. Deviation .448 Minimum 0 Maximum 1 Range 1 Interquartile Range 1 Skewness 1.006 .119 Kurtosis -.993 .237 Here mean and median are approximately equal, the data distribution are approximately normal distribution also positively skewed and plateo kurtic. Tests of Normality Kolmogorov-Smirnova Shapiro-Wilk Statistic df Sig. Statistic df Sig. Gender .455 424 .000 .559 424 .000 a. Lilliefors Significance Correction The test for normality is significant. For the variable Student Neuroticosm Case Processing Summary Cases Valid Missing Total N Percent N Percent N Percent Student Neuroticosm 420 97.7% 10 2.3% 430 100.0% Descriptives Statistic Std. Error Student Neuroticosm Mean 23.6262 .41985 95% Confidence Interval for Mean Lower Bound 22.8009 Upper Bound 24.4515 5% Trimmed Mean 23.6534 Median 24.0000 Variance 74.034 Std. Deviation 8.60431 Minimum .00 Maximum 44.00 Range 44.00 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 Kolmogorov-Smirnova Shapiro-Wilk 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. For the variable Student Extroversion Case Processing Summary Cases Valid Missing Tota...
