# Pre-Calculus: Sets

A set is a collection of distinct objects considered as a whole. Sets are one of the most fundamental concepts in mathematics. The study of the structure of sets, set theory, is rich and ongoing.

Many students find sets difficult. They feel overwhelmed with sets homework, tests and projects. And it is not always easy to find sets tutor who is both good and affordable.

Finding The Median Of A Data Set
Video Clip Length: 2 minutes 17 seconds

This tutorial will be able to show you how to find the median of a given data set.  It is important to know that placing the numbers in least to greatest will greatly help you figure your median.   A median is the exact middle or the number that lies in the middle of your data set.  To figure it out in a odd numbered set, it will be an exact number in the set, but if it is an even numbered set, then you must find the average of the two numbers in the middle.

Two page memo with Venn Diagram
Market segmentation is known as the process of dividing up a market for goods or services into smaller groups. For example, a market may be segmented into geographics (location), demographics (income, age, gender, etc.), and psychographics (personality, lifestyle, values, etc.).

After running various advertisements, you have received the statistics from each market segmentation. A total of 1,800 ads were run to try and reach the various segments. The following lists the breakdown of each:

680 for a geographic location
500 based on demographics
440 based on psychographics
385 based on both geographic and demographics
245 based on both geographic and psychographics
325 based on both demographics and psychographics
245 based on all three segments

Write a memo to your boss that displays the data graphically in a Venn diagram. Also, describe example scenarios listed below by first constructing them in set notation (use the addition principle to show the union values) and then give the actual values. Then, construct a table to summarize the data.

Ads that were run either for geographics or demographics
Ads that were not run for geographics
Ads that were run for geographics and psychographics but not for demographics
Ads that were not run for any of these segments (e.g., behavioral basis)
Ads that were not run for geographics but were run for demographics
