It is the midpoint of a given class interval.*1 pointA) Class sizeB) RangeC) MidpointD) Class mark

How is the midpoint of a class interval calculated? By subtracting the lower limit from the upper limit By adding the lower limit to the upper limit and dividing by 2 By multiplying the lower limit with the upper limit By dividing the lower limit by the upper limit

The class mark of a class is defined to be the (average, minimum, maximum) of the upper and lower limits of the class.

Class Interval: 0-10  10-20  20-30  30-40  40-50  50-60  60-70Frequency: 3, 5, 1, 2, 4, 3, 2The range of the above data is:a.0b.10c.60d.70

Write the midpoint formula

The representative number that captures the range spanned by the data points is called ___
