Consider the following data representing the price of laptop computers (in dollars). 1262, 1302, 1306, 1348, 1269, 1345, 1058, 1334, 1270, 1240, 1153, 1177, 1127, 1195, 1293, 1122, 1168, 1214, 1177, 1116, 1126 Price of Laptop Computers (in Dollars) Class Frequency Class Boundaries Midpoint Relative Frequency Cumulative Frequency 1053–1102 1103–1152 1153–1202 1203–1252 1253–1302 1303–1352 Step 5 of 7 :
Identify the midpoint of the third class.
Midpoint = (upper class + lower class)/2
For 3rd class, upper class = 1202 and lower classs = 1153
this gives us
Midpoint =(1202+1153)/2
or
midpoint = 1177.5
