Mean, Median, Mode, and Range Worksheet

As budding scientists, stock market brokers, marketing geniuses, and many other professionals, we often find ourselves managing data on a daily basis. Statistics has numerous applications in various fields of study, making it an essential tool for anyone who works with numbers. In this article, we will explore the concept of mean, median, mode, and range, and provide a worksheet to help you practice your skills.

In statistics, measures of central tendency are used to describe a dataset's typical value or average. There are several types of measures of central tendency, including the mean, median, mode, and range. Each of these measures has its own strengths and weaknesses, making them useful in different situations.

The mean is the average of a dataset, calculated by adding up all the values and dividing by the number of data points. For example, if we have the following dataset: 2, 4, 6, 8, 10, the mean would be (2 + 4 + 6 + 8 + 10) / 5 = 6.

The median is the middle value in a dataset when it is arranged in order. In the previous example, the median would be 6, as it is the middle value of the dataset.

The mode is the most frequently occurring value in a dataset. For example, if we have the following dataset: 1, 2, 2, 3, 4, the mode would be 2, as it appears twice, more than any other value.

The range is the difference between the largest and smallest values in a dataset. In the previous example, the range would be 10 - 2 = 8.

Now that we have covered the basics of mean, median, mode, and range, let's practice with a worksheet:

Worksheet:

1. Find the mean of the following dataset: 3, 5, 7, 9

2. Find the median of the following dataset: 1, 3, 4, 6

3. Find the mode of the following dataset: 2, 4, 4, 6, 8

4. Find the range of the following dataset: 10, 15, 20

Answers:

1. The mean is (3 + 5 + 7 + 9) / 4 = 6.

2. The median is 4, as it is the middle value of the dataset.

3. The mode is 4, as it appears twice more than any other value.

4. The range is 20 - 10 = 10.

By practicing with this worksheet and understanding the concept of mean, median, mode, and range, you will be better equipped to analyze and interpret data in your future endeavors.
