Assignment 2

DEVELOPING INTIMACY WITH YOUR DATA

This exercise involves you working with a dataset of your choosing. Visit the Kaggle website, browse through the options and find a dataset of interest, then follow the simple instructions to download it. With acquisition completed, work through the remaining key steps of importing, exploring and examining your data to develop a robust familiarization with its potential offering:

Thoroughly examine the physical properties (type, size, condition) of your dataset, noting down useful observations or descriptions where relevant.

What could you do/would you need to do to clean or modify the existing data to create new values to work with? What other data could you imagine would be valuable to consolidate the existing data?

Using a tool of your choice (such as Excel, Tableau, R) to visually explore the dataset in order to deepen your appreciation of the physical properties and their discoverable qualities (insights) to help you cement your understanding of their respective value. If you don’t have scope or time to use a tool, use your imagination to consider what angles of analysis you might explore if you had the opportunity? What piques your interest about this subject?

(You can, of course, repeat this exercise on any subject and any dataset of your choice, not just those on Kaggle.)

Use the Explore command to compare the income levels (rincdol) for both genders (sex). Go to the Resources area of the class to download the files that you will need to complete your assignments each week. Open gss.sav in SPSS, and complete the following calculations to determine the differences in the income level between males and females.

Compute the following for each group:

1. Mean
2. Median
3. Quartiles
4. Range
5. Variance
6. Standard deviation
7. Skewness
8. Kurtosis

The Explore command will also produce several different types of plots. Click on the Plots button, and create the following plots for each group:

1. Histograms (include the normal curve on the histogram)
2. Box plots
3. Stem-and-leaf plots

Use the calculations and plots to answer the following questions. When discussing a calculation, include the value in the text to bolster your analysis.

1. What can you determine from the measures of skewness and kurtosis relative to a normal curve?
2. What are the mean and median?
3. Does the mean or median seem better to represent the scores? How have extreme scores impacted these values?

Submit your output from all SPSS analysis as an SPSS output file and your Word document.
