Unit 10 Discussion

Statistics

In today’s world you are inundated with statistics. Being able to understand the terminology and sort through the data in a way that gives you an accurate picture of the results is an important skill to have.

Initial Response Post

You are searching for a home in your area. A realtor has given you the median home price for the area. You would like to determine whether the mean, median, or mode home price best represents home prices in your area.

Find a website that will allow you to search home prices in your area using specific criteria. Choose at least three criteria (number of bedrooms, square footage, lot size, garage size etc.) to narrow your search and find the prices of at least 10 homes. Do not use price as one of the criteria as you need a variety of prices to come to a conclusion about housing prices in the area.

List the criteria you chose.

List the prices of the homes that you found (include the URL in your post).

Calculate the mean, median, and mode of your home prices showing all steps used.

Explain which of the three measurements you feel best represents the home prices in your area and why.

The addition of even one piece of data to a collection of data can have a significant impact on the calculations of mean, median, and mode. Find a classmate’s post that has not been replied to. Use the same criteria that your classmate used in their home search to search homes in your area.

List the price of the first home that appears in your search. Without doing the actual calculation, describe what you think will happen to the mean, median, and mode if you were to add your home price to the home price data collected by your fellow classmate. Do you think you will see a significant increase/decrease, a slight increase/decrease, or no change?
