Statistics Frequency Distribution

In a frequency distribution the class having maximum frequency is called the modal class

• TRUE

• FALSE

The abscissa of the point of intersection of less than type and more than type cumulative frequency curves of a grouped data gives its

• Mean

• Median

• Mode

• Class

The relationship between mean, median and mode is

.............median = 2 .......... + ...........

• 2,median, mode

• 3,median, mode

• 2,mean, mode

• 3,mean, mode

Which one of the following measures is determined only after the construction of cumulative frequency distribution?

• Mean

• Median

• Mode

• None of the above

Two ogives less than and more than type for the same data intersect at the point P. The y-coordinate of P represents

• Modal

• Range

• Cumulative frequency of the median class

• Median

In the class interval 50-55 what is the Upper limit?

• 50

• 55

• 49.5

• 54.9

The mode of a frequency distribution is obtained graphically from

• a frequency curve

• a frequency polygon

• a histogram

• an ogive

An ........... is a freehand graph showing the curve of a cumulative frequency distribution

• Ogive

• Bar graph

• histogram

• None of the above

It is assumed that the frequency of each interval is centred around its

• mid point

• lower limit

• upper limit

• none of the above

It is the branch of Mathematics that deals with collecting, organizing,

and interpreting data to address a certain phenomenon.

• Population

• Statistics

• Sample
