# Excel data analysis | Computer Science homework help

X1 in the EXCEL file corresponds to question 1.

X15 corresponds to question 15 etc.

You must complete these analytic functions for all 59 questions: X1 – X59.

• Descriptive Statistics
• Histogram (bar chart) with Frequency Distribution Table and Pie Chart with labels
• Correlation
• Regression

The data is coded.

For some questions the coding is 1-10 for an interval scale and others 1-5 for a 5 point Likert scale.

Not all scales in this questionnaire have the same descriptors. You must read the questionnaire.

It is impossible to interpret the data without referring to the questionnaire.

Some questions include scales that use these 5 descriptors

(Strongly Agree, Agree Undecided, Disagree, Strongly Disagree) and other questions include scales that use 5 different descriptors.

Descriptive Statistics

You will use EXCEL to generate the Descriptive Statistics for all variables: X1 – X59.

You must interpret and in explain in words the Mean.

Histograms

You will create histograms (bar charts) with frequency distribution tables and pie charts with labels.

Labels are important since color coded pie slices may not always be viewed in color.

After clicking DATA, DATA ANALYSIS, and then HISTOGRAM

EXCEL will ask you for input and the BIN.

You will need to create a table in EXCEL which lists the coding for the Bin Input.

The BIN is 1, 2, 3, 4, 5 for some questions and you should include the descriptors Strongly Agree, Agree, Undecided, Disagree, Strongly Disagree, and Not Applicable.

For other questions the BIN will be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

Correlation

Determine the Pearson Correlation Coefficient for:

Gender and Satisfaction with Your Car (X16)

Gender and Color (X22)

Place of Birth and Employment Status

Regression

Use EXCEL to generate a regression analysis for:

Dependent Variable: X 16 – Level of Satisfaction

Independent Variables: X17, X18, X19, X20, X21, X22, X23, X24 and X25.
