Which variables in the dataset are approximately normally distributed/scale?

4.1.For the variables with five or more ordered levels, compute
the skewness. Describe the results. Which variables in the dataset are
approximately normally distributed/scale? Which ones are ordered but not
normal?
4.2.Do a stem-and-leaf plot for the same-sex parent’s height split
by sex at birth. Discuss the plots.
4.3.Which variables are nominal? Run Frequencies for the nominal
variables and other variables with fewer than five levels. Comment on the
results.

4.4.Do boxplots for student height and for hours of study. Compare
the two plots. Make
Sure to:

1.
Attach
your word document for review
2. Write the problem
number and the problem title as a level one heading (Example ‐ A.1.1: Chapter
2, Problem 2.1, and then provide your
response.
3. Use level two headings
with short titles
for multi part questions (Example
‐ A1.1.a, Short Title,
A1.1.b, Short Title II, etc.)
4. Use appropriate level headings for key elements
of your discussion such as Research Questions, Hypotheses, Descriptive
Statistics, Assumptions & Conditions, Interpretation, Results, and others.
Your goal is to make your analysis easy to follow and logical.
5.
Ensure
that all tables and graphs are legible and include a figure number.
6. Carefully review
your document prior to submission for formatting, flow, and readability. Keep
in mind that running the statistical tests is only the first half of the
challenge; you must be able to clearly communicate your findings to the reader.
