Practice finding the median of a data set. Like the mean, the median gives us a sense of the middle, or center, of the data.

The median is the middle number when you arrange your numbers from smallest to largest. If you have an even number of values, the median is the average of the two middle numbers.

This video shows how the mean and median can change when the outlier is removed. So, if a scientist does some tests and gets an outlier, he/she can remove it to change the results to what he/she wants.

The median is the middle value of a set of numbers. You'll need to set the values from least to greatest before finding the median. If there are an even number of values within a dataset, the median is the …

If the set of numbers is odd, then the median will be the middle number in the set. If the set of numbers is even, then the median will be the average between the two middle numbers in the set.

Here we give you a set of numbers and then ask you to find the mean, median, and mode. It's your first opportunity to practice with us!

Median is a little challenging at first, but once you get the hand of adding and dividing the numbers, it's quite easy!

Mode is not the best measure of center. I think you meant median. Yes, mode is the best measure of center, but the mean would be the best on any other statistical data set because it's the average. It's …

To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3).

Normal distributions come up time and time again in statistics. A normal distribution has some interesting properties: it has a bell shape, the mean and median are equal, and 68% of the data falls …
