Get Excel Exercise #10: Statistical Analysis

This guide aims to provide clear and comprehensive instructions for filling out the EXCEL EXERCISE #10: Statistical Analysis form online. Follow the steps below to ensure your completion of the statistical analysis with accuracy and efficiency.

Follow the steps to successfully complete the statistical analysis form.

1. Click 'Get Form' button to download the EXCEL EXERCISE #10: Statistical Analysis form and open it in your preferred editor.
2. Begin by entering the data for the variables URBAN (percent living in urban areas), MURDER (murders per million residents), ROBBERY (robberies per million residents), POLICE (police employees per 100,000 population), and REGION for the 50 states. This data should be labeled on the sheet as DATA.
3. Copy the columns A1:B52 (STATE and MURDER) to a new tab labeled UNIVARIATE for further analysis.
4. Calculate the variance for MURDER using the formula Σ(Xi-Xbar)²/(N-1). Start by labeling cells A54 to A58 with 'Mean =', 'N =', 'Variance =', and 'Std Dev ='.
5. Input the following formulas: in cell B54, enter =average(b3:b52) to calculate the mean; in cell B55, enter =count(b3:b52) to count the number of cases, and in cells C3 and D3 enter =b3-$b$54 and =c3^2, respectively.
6. Drag to copy formulas in C3 and D3 down to cells C52 and D52 to calculate the squared deviations.
7. In cell D54, sum the deviations squared by inputting =sum(d3:d52) to facilitate variance calculation.
8. To find the variance, in cell B57 use =d54/(b55-1), and to calculate standard deviation, in cell B58 enter =sqrt(b57).
9. For skewness and kurtosis, label cells A59 and A60, and use the formulas for Skewness =(N/((N-1)(N-2)))*(E54/(Std Dev^3)) and Kurtosis =(((N*(N+1))/((N-1)(N-2)(N-3))) * (F54/(Std Dev^4))) - ((3*(N-1)²)/((N-2)(N-3))).
10. Conduct a frequency distribution by defining intervals in cells H3 to H6 and using the FREQUENCY function based on your MURDER data range.
11. Move on to Bivariate statistics by copying relevant data into a new sheet labeled BIVARIATE, and calculating correlation coefficients using the appropriate formulas.
12. Lastly, create a scatterplot by selecting your data and using the charting functions in your spreadsheet software.
13. Once all analyses are complete, ensure to save the changes, download, print, or share the form as needed.
