26+ Calculating Class Boundaries

By using this class mark formula you can easily find. On the other hand the upper boundary of each class is.

Find The Mode Of The Following Distribution Class Interval 10 14 14 18 18 22 22 26 26 30 30 34 34 38 38 42 Frequency 8 6 11 20 25 22 10 4

If the class is something like 0.

. The lower boundary of each class is calculated by subtracting half of the gap value 001 2 0005 001 2 0005 from the class lower limit. The lower boundary of each class is calculated by subtracting half of the gap value 1 2 05 1 2 05 from the class lower limit. Begingroup If the class is something like 1-5 6-10 11-15 then lower class boundary is 05 for the first class and lower class limit is 1.

BUT Sometimes the class boundaries are a bit confusing. On the other hand the upper boundary of. Thus we have Mid-point LCL UCL 2 or Mid-point LCB UCB 2 Referring to the distribution of weight of 36 students the mid-points for the first two class intervals are 44.

You work with age groups like. Class Boundaries Because of rounding the stated class limits do not correspond to the actual ranges of data falling in them. The formula to calculate class mark in a frequency distribution is given as upper limit lower limit2 or Sum of class boundaries2.

For example if the class limits are 100 and 200. Class boundaries are related to class limits by the given relationships. For the classification of overlapping or classification of mutually exclusive which.

As a result of the above the lower class boundary of one class is equal to the upper class boundary of the previous. You just go halfway between the class limits. The total frequency of all values less than the upper class boundary of a given class interval is called the cumulative frequency up to and including the class interval.

The class intervals actual class limit is called the class boundary.
