Lab Assignment for Chapters 2 and 3 MATH
1342 / 2342 – Introductory Statistics
Instructor: David Katz
Your first lab assignment is to analyze residential real estate data by creating a frequency table and a histogram. This assignment should include two main parts.
1) Locate & record the raw data – look
for residential real estate data at the website for your local county appraisal
district. For example, look up a residential street or two within
a) Street Address
b) Current Appraised Value
c) Square Feet for Living Area
2) Do the statistical analysis – show the mathematics behind the data.
a) Create a frequency table for the appraised values in your data set. Use the guidelines on page 44 for making the table. For example, a good table will have from 5 to 20 classes or rows of information.
b) Using your frequency table, construct a histogram based on the guidelines on pages 51-52. Be sure to label what is measured on the horizontal (x-axis) and on the vertical (y-axis).
c) Include descriptive captions (one sentence is adequate) for both the frequency table and histogram.
d) Compute the mean, median, and standard deviation for your data. Show the arithmetic, formulas and/or calculator steps you use in these computations. Specify the units of measurements for the mean, median, and standard deviation.

Typing the report is not necessary, but remember neatness counts! If I cannot read your report, I cannot grade it! Your finished report should be about 2-3 pages.
I encourage you to work together with your classmates to help write up the lab and check each other’s computations. However, do NOT just copy verbatim a classmate’s lab report and hand it in as your own!
You will want to be sure to collect good data on your own because you will be re-using this same data to complete lab #4 later this semester.
