Ogive quick CFU

Using the ogive shown below, what is the cumulative frequency of data values less than or equal to 16 ?

• 60

• 66

• 30

• 20

What is an ogive graph?

• Cumulative Frequency Graph
• Frequency Graph
• Relative Frequency Graph
• A pie chart

The horizontal axis of an ogive comes from this part of the frequency table:

• Class

• Frequency

• Midpoint

• Cumulative Frequency

• Class Endpoints

The vertical axis of an ogive comes from this column:

• Class

• Frequency

• Midpoint

• Cumulative Frequency

• Class Endpoints

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 greatest increase.

• 5

• 10

• 15

• 20

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

• 36

• 43

• 48

• 51

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

• 62

• 64

• 66

• 68

What is the difference between a frequency polygon and an ogive?

• A frequency polygon displays class frequencies while an ogive displays cumulative frequencies

• A frequency polygon is a line graph while an ogive is a histogram

• It is easier to find patterns in the data from a frequency polygon than an ogive.

• There is no difference between a frequency polygon and an ogive.
