In this video, we're going to use Minitab
Express to create a pie chart
I'm going to do this homework problem as an example
so first I need to copy the data into Minitab
and again, I have a data table here that is showing the percentage in each category, not raw data
so I click on the two blue boxes and copy to clipboard
use tab delimiter, and command or ctrl + C to copy
I do have a header row in this table, that says label, education level, and percentage
so when I paste into Minitab, I'm going to paste into the top row
now to create my pie chart, I go up to graphs
and go down to pie chart, which is almost at the bottom
now what I have in this case is summarized data
if I had the raw data, which would look like a list of names and then every person's education level
then I would use counts of unique values
when you do the data analysis assignment, that's what you're going to have
so you would choose counts of unique values
in this case, I'm going to choose summarized data
my category names, I'm going to choose label, so that it labels the slices with A, B, C, D, and E
and then percentage for summary values
because I want Minitab to use the percentages in the table when it makes the slices of the pie
click OK
now it's going to give me an error message
it says category names and summary values must have the same number of rows
and if I look at the table, I see that the problem is here in the bottom row
this row says total 100, that's not actually a slice of the pie
so I don't want to have that in my pie chart, I just want to have the percentages
so I'm going to highlight those two rows and delete them
and then try to make my pie chart again, so click on graphs, pie chart
summarized data, category names is label, summary values is percentage, and click OK
now here's my pie chart
and the percentages match with the percentages in my data table, which is
good
now if I click on the pie chart, anywhere, it brings up my plus sign
I want to click on that, and choose slice labels
I want to have slice labels checked, and click on the arrow to bring up more options
I want to label my slices with category name and percent
and use a leader line, which is going to connect the category label to the slice
and that's how you make a pie chart in Minitab Express
