Data Analysis: Descriptive Statistics and Assumption Testing Correlation: Descriptive Statistics and Assumption Testing To determine whether they met the assumptions required for parametric testing, the data were observed both visually and statistically. The histogram below shows a distribution of frequencies approximately normal (bell shaped) of the data absent from outliers. In addition, the following descriptive statistics confirm skewness and kurtosis within acceptable -2 and + 2 mean, median, and mode are also closely aligned, which occurs with a normal distribution of data. descriptive statistics confirm that the data are suitable for data analysis using parametric statistical procedures. The correlation coefficient of r= -0.715 indicates that particulate matter size, as measured in microns is strongly and negatively correlated with mean annual sick days per employee. R2=.51 indicate that 51 percent of the variability inn employee sick days is explained by particulate Bin Frequency 2 1 2 1 4 5 5 13 6 18 7 24 8 18 9 12 10 7 Mor e 2 microns Sick days per employee microns 1 Mean annual sick days per employee -0.715984185 1 SUMMARY OUTPUT Regression Statistics Multiple R 0.715984185 R Square 0.512633354 Adjusted R Square 0.507807941 Standard Error 1.819897828 Observations 103 ANOVA Df SS MS F Significanc e F Regression 1 351.8572001 351.8572 106.2362 1.89E-17 Residual 101 334.5148387 3.312028 Total 102 686.3720388 Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Lower 95.0% Intercept 12.65057929 0.701790055 18.02616 2.47E-33 11.25842 14.04274 11.25842 X Variable 1 -0.981348321 0.095210965 -10.3071 1.89E-17 -1.17022 -0.79248 -1.17022 2 2 4 5 6 7 8 9 10 More 0 5 10 15 20 25 30 Correlation Data Bin Frequency

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
