Creating a Frequency Distribution for Grouped Data: Step 1 Determine the minimum and maximum values, and how many classes you need
Creating a Frequency Distribution for Grouped Data: Step 2 Find the class width: Class Width = __Range__ # of classes *ALWAYS round up to the next whole number
Creating a Frequency Distribution for Grouped Data: Step 3 Write your minimum value as your lowest lower limit Class Limits Minimum value 2
Creating a Frequency Distribution for Grouped Data: Step 4 Add the class width to your lower limit to find the next lower limit; WRITE BELOW NOT BESIDE! (do all lower limits first) Class Limits Ex: Class width = 9 2 11 20 29 Go until you have the amount of classes needed
Creating a Frequency Distribution for Grouped Data: Step 5 To find each upper limit, subtract one from the next lower limit Class Limits 2 - 10 11 - 19 20 - 28 29
Creating a Frequency Distribution for Grouped Data: Step 6 To find last upper limit, add class width to the 2nd to last upper limit Class Limits 2 - 10 11 - 19 20 - 28 29 - 37
