Analyzing Statistics

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

• Mean

• Median

• Mode

• None of the above

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

The mean, median and mode of grouped data are always different

• TRUE

• FALSE

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

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

the most frequently occurring value(s) in a set of data

• mode

• median

• shape

• range

the difference between the highest and lowest values in a set of data

• median

• range

• mode

• shape

the middle number of a set of values that are ordered from least to greatest

• median

• mean

• mode

• range
