Frequency Polygon and Ogive

The graphical representation of a cumulative frequency distribution is called

• Bar graph

• Histogram

• Frequency polygon

• Ogive

An ogive is used to determine

• Standard deviation

• Median

• Mode

• Mean

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

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

• Ogive

• Bar graph

• histogram

• None of the above

Use the ogive to approximate the height for which the cumulative frequency is 25.

• 62

• 64

• 66

• 68

Use the ogive to approximate the cumulative frequency for a height of 72 inches.

• 36

• 43

• 48

• 51

Use the ogive to approximate the location of the greatest increase in frequency.

• 58 - 60

• 60 - 62

• 62 - 64

• 64 - 66

Use the ogive to approximate the number in the sample.

• 100

• 28

• 80

• 341

Use the ogive to approximate the greatest increase.

• 5

• 10

• 15

• 20

Complete the definition:

• class boundaries

• lower class limits

• upper lass limits

• midpoints
