Assignment | Call International oversees

Call International oversees the quality of 200 call centers throughout the world. They want to determine how the centers compare among four variables for the most recent year:

Shift A Average Call Time (in minutes)
Shift B Average Call Time (in minutes)
Average Customer Satisfaction Level (on a 4-point scale: 1=poor, 2=average, 2=good, 3=excellent)
Average Number of Employees

Data collected for the sample of 200 Call Centers is contained in the file named Call Centers linked at the bottom of the page. Use all 200 data points.

Managerial Report

Prepare a report (see below) using the numerical methods of descriptive statistics presented in this module to learn how the variables contribute to the success of a call center. Be sure to include the following three items in your report.

Find descriptive sample statistics (mean, median, range, the two quartiles Q1 and Q3, minimum, maximum, sample standard deviation, and coefficient of variation) for each of the four variables, along with an explanation of what the descriptive statistics tell us about the call centers.
Use the z-score to determine which call centers, if any, should be considered outliers in each of the four variables. If there are any outliers in any category, please list them and state for which category they are an outlier.
Compute the sample correlation coefficient, showing the relationship between Satisfaction Level and each of the other three variables (Shift A Average Call time, Shift B Average Call Time, Average Number of Employees). Explain what the correlation coefficients tell us about the three pairs of relationships. Use tables, charts, or graphs to support your conclusions.

The body of your paper should answer the questions posed in the problem. Explain how you approached and answered the question or solved the problem, and, for each question, show all steps involved. Be sure this is in paragraph format, not numbered answers like a homework assignment.
The conclusion should summarize your thoughts about what you have determined from the data and your analysis, often with a broader personal or societal perspective in mind. Nothing new should be introduced in the conclusion that was not previously discussed in the body paragraphs.
Include any tables of data or calculations, calculated values, and/or graphs associated with this problem in the body of your assignment.
Document formatting, citations, and style should conform to the CSU-Global Virtual Library CSU-Global Guide to Writing and APA: Introduction (Links to an external site.)Links to an external site.. A short summary containing much that you need to know about paper formatting, citations, and references is contained in the New Sample APA Paper (Links to an external site.)Links to an external site..

SAMPLE SOLUTION

Call International Oversees

With the advent of technology, communication has come up as a basic way through which technology is manifested. Different communication service providers across the world have different call rates. Based on call rate per minute and calling patterns, among other factors, statistical analysis becomes important for any researcher. This essay is meant to analyze the quality of 200 call centers in the world based on the number of employees they have and average time of call. Descriptive statistics will be carried out to show what they imply for the different call centers. Finally, the essay will also show the correlation between the number of employees and the other three variables.

What the descriptive Statistics say about the call centers The mean values presented give a lot of information about the 200 call centers. As a measure of central tendency, the statistical mean normally explains where the data is highly clustered. In this case, four statistical means have…
