In this video, I'm going to show you how to use Minitab 18 to create a pie chart
we're going to do this homework problem as an example
so notice with this homework problem
I have a summary table here that shows the percentage of people who responded with each education level
I do not have raw data
so I'm going to copy my data table, copy to clipboard, use tab delimiter, and then click copy
I do have a header row here that says label, education level, and percentage
those are headers, so when I paste into Minitab, I'm going to paste into the top row
once I've pasted my table, to make my pie chart, I go to graph
and then go down towards the bottom, click on pie chart
since I do not have raw data, I have a table, I'm going to choose chart values from a table
then when I click in the categorical variable box, it brings up options for the categorical variable
I have to click in that box in order to get those options
my categorical variable, I'm going to use label, because I want to label them with A, B, C, and D
so choose that, and hit select
for summary variables, I'm going to choose percentage
because I want each slice to show the percentage of people that responded in each way
so click on percentage, and then click select
now I'm going to click on labels, go over to slice labels
I want to label the pie slices with category name, percent, and draw a line from label to slice
this will make my graph easier to read
I click OK, and then click OK again
now something strange happened, I have this blue slice here that is 50%
and what Minitab did was they made a slice for this total category
and that's not what I want, because 100% is the total of these percentages, it shouldn't be a slice on its own
so what I need to do is highlight this row and delete it
so I go to edit and clear cells
that takes the row away, and now I'm gonna make my pie chart again
so go to graph, pie chart
it saved the options in here that I selected, so I can just click OK
and I will get a new pie chart, now this one looks better, if I look at the percentages
each percentage matches what I have in the table
and that's how you make a pie chart in Minitab 18
