Statistics assignment

Instructions

Objective: Analyze the dataset and begin writing sections of your final report.

Instructions:

You will submit two files:

1. A written report (Word file or typed directly)
2. An Excel file showing your calculations and graphs

Steps:

Identify Variables

• List each variable in the dataset.
• State whether the variable is qualitative or quantitative.
• Identify the scale of measurement (nominal, ordinal, interval, ratio).

Descriptive Statistics

• For each quantitative variable, compute measures of center (mean, median).
• Compute measures of spread (IQR, standard deviation).
• Comment on any potential outliers.

Graphical Analysis

• Choose one variable and create a histogram.
• Use the graph to discuss the shape of the distribution (symmetrical, right-skewed, left-skewed).

Written Summary

• Write a 150200 word report summarizing your findings. Include:
• How the variables are measured
• Center and spread of the data
• Shape of the distribution
• Presence or absence of outliers

Tips:

• Use the Excel lab manual as needed.
• Functions like AVERAGE() and STDEV.S() can be used for calculations.
• This assignment will contribute to your methods and descriptive results section of the final case study report.
