Statistics

An ogive is used to determine

• Standard deviation

• Median

• Mode

• Mean

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

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

• Mean

• Median

• Mode

• None of the above

If the median of the data 4, 7, x-1, x-3, 16, 25 written in ascending order is 13 then x is equal to

• 13

• 14

• 15

• 16

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

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
