How to Find the Median in Minitab
The median in statistics is the middle number of a data set. The median is part of “Descriptive Statistics” in probability and statistics; descriptive stats like mean, mode and median give you some basic information about the size and scope of a data set. Finding the median involves ordering your numbers from smallest to largest and then locating the middle number. This can be a time-consuming task for very large datasets but you can find the median in Minitab in a couple of clicks.
Sample problem: Find the median in Minitab for the following set of numbers: 123, 125, 126, 127, 127, 128, 129, 159, 214, 237, 238, 254, 256, 258, 259, 321, 325, 357, 451, 452, 452, 453, 456, 456, 457, 458, 458, 459, 651, 652, 652, 653, 654, 657, 658, 659, 741, 742, 748, 753, 754, 759, 765, 785, 789, 798, 852, 963, 987.Step 1: Type your data into one column in a Minitab worksheet. If you’ve used Excel, Minitab works the same way. If you haven’t entered data into a worksheet before:
- Type the first number (in this case, 123) into the top left cell.
- Click on the cell immediately below and enter the next number.
- Continue down the column until all the numbers have been entered. Don’t skip any cells (i.e. don’t leave any blank spaces).
Step 2: Click “Stat”, then click “Basic Statistics,” then click “Descriptive Statistics.”
Step 3: Click the variables you want to find the median for and then click “Select” to move the variable names to the right window.
Step 4: Click “Statistics.”
Step 5: Check the “Median” box and then click “OK” twice. The median will be displayed in a new window. The median for this particular set of numbers is 457.
Tip: It may take you a few minutes to type in your dataset, but once you have you can perform any number of statistical calculations in Minitab on the set without having to retype it.Comments are now closed for this post.
