Answer 1

Statistics ExamplesStep-by-Step Examples Statistics Frequency Distribution Find the Upper and Lower Class Boundaries of the Frequency TableClassFrequency2−10111−19320−289ClassFrequency2-10111-19320-289The lower limit for every class is the smallest value in that class. On the other hand, the upper limit for every class is the greatest value in that class.ClassFrequency(f)LowerLimitsUpperLimits2−10121011−193111920−2892028ClassFrequency(f)LowerLimitsUpperLimits2-10121011-193111920-2892028Class boundaries are the numbers used to separate classes. The size of the gap between classes is the difference between the upper class limit of one class and the lower class limit of the next class. In this case, gap=11−10=1gap=11-10=1.gap=1gap=1The lower boundary of each class is calculated by subtracting half of the gap value 12=0.512=0.5 from the class lower limit. On the other hand, the upper boundary of each class is calculated by adding half of the gap value 12=0.512=0.5 to the class upper limit.ClassFrequency(f)LowerLimitsLowerBoundariesUpperLimitsUpperBoundaries2−10122−0.51010+0.511−1931111−0.51919+0.520−2892020−0.52828+0.5ClassFrequency(f)LowerLimitsLowerBoundariesUpperLimitsUpperBoundaries2-10122-0.51010+0.511-1931111-0.51919+0.520-2892020-0.52828+0.5Simplify the lower and upper boundaries columns.ClassFrequency(f)LowerLimitsLowerBoundariesUpperLimitsUpperBoundaries2−10121.51010.511−1931110.51919.520−2892019.52828.5ClassFrequency(f)LowerLimitsLowerBoundariesUpperLimitsUpperBoundaries2-10121.51010.511-1931110.51919.520-2892019.52828.5Add the lower and upper class boundaries columns to the original table.ClassFrequency(f)LowerBoundariesUpperBoundaries2−1011.510.511−19310.519.520−28919.528.5
