Answer 1

Answer:

1. Answer:The class intervals: are the subsets into which the data is grouped. The width of the class intervals will be a compromise between having intervals short enough so that not all of the observations fall in the same interval, but long enough so that you do not end up with only one observation per interval.

The width of the class intervals will be a compromise between having intervals short enough so that not all of the observations fall in the same interval, but long enough so that you do not end up with only one observation per interval.Class limits:The upper class limit of a class is the largest data value that can go into the class. Class limits have the same accuracy as the data values; the same number of decimal places as the data values. Class boundaries. They are halfway points that separate the classes.

It is defined as the average of the upper and lower class limits.

Answer 2

Answer:

1. Class Interval-The class intervals are the subsets into which the data is grouped. The width of the class intervals will be a compromise between having intervals short enough so that not all of the observations fall in the same interval, but long enough so that you do not end up with only one observation per interval.
2. Class Limit-The lower class limit of a class is the smallest data value that can go into the class. ... The upper class limit of a class is the largest data value that can go into the class. Class limits have the same accuracy as the data values; the same number of decimal places as the data values.
3. Class size- class size is the average number of students per class, calculated by dividing the number of students enrolled by the number of classes.
4. Class Mark-Class Mark (Midpoint) The number in the middle of the class. It is found by adding the upper and lower limits and dividing by two. It can also be found by adding the upper and lower boundaries and dividing by two.
