Ck 12: Statistics: Standard Deviation of a Data Set

You already know that the mode of a data set is the number that occurs most often in the set. But what if all of the numbers in the set occur the same number of times? I could tell you the answer, but I think you should watch the video.

Looking for the range of a set of numbers? Well, that means you are looking for the difference between the largest value and the smallest value. So first, write the numbers in order from least to greatest. Then identify the largest value...

Mode, the number that occurs most often. A data set could have one mode, no modes, or multiple modes. The teacher explains these variations and even gives some example of non-numerical data and how to figure out the mode.

The data sample comes from the number of glasses of water consumed each day by 15 students. You are trying to find minimum, maximum, median, and quartile from this data set. Minimum is the smallest number that occurs, while maximum is...

Find the standard deviation of a set of integers. Using the formula to find the standard deviation, the instructor shows you how to apply the formula to a small set of integers.

Mean, mode, median? What's the difference? How do you find them? The teacher focuses on explaining median in this video. She gives a good explanation and shows several examples using different sets of numbers.

The data sample comes from the number of glasses of water consumed each day by 15 students. You are trying to find minimum, maximum, median, and quartile from this data set. Minimum is the smallest number that occurs, while maximum is...

No need to nap through the lesson. Given data on the number of naps two teachers take, learners calculate the mean, median, mode, and range, and then interpret their results in terms of the context. They then see how to determine the...

This tutorial illustrates the entire process of finding the standard deviation of a data set. [6:17]
