Describing Data
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...

How Do You Find the Range of a Data Set?
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...

How Do You Find the Mean of a Data Set?
There are eight decimals numbers in this data set. Find the mean. So add all the terms together and then divide that total number by the number of terms in the data set. That's how you find the mean or average of a data set.

How Do You Find the Mode of a Data Set?
What is the mode of a data set? Mean, mode, median. Get confused in remembering which is which? Mode is the number that appears the most times in a data set. So given a data set, arrange the numbers in numerical value from least to...
Curated OER
What is the Mode of a Data Set?
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.

What is the Mean of a Data Set?
Average, mean, average, mean. They are the same thing. So just use the formula for finding the average of a set of numbers to get the mean. Add up the value of the terms and then divide by the number of terms in the data set. There's the...
