Which of the following best defines a quartile?

• A value that divides the data into two equal parts

• A value that divides the data into three equal parts

• A value that divides the data into four equal parts

• A value that divides the data into five equal parts

Deciles are measures of position that divide the data into:

• 5 equal parts

• 10 equal parts

• 20 equal parts

• 4 equal parts

A percentile is defined as:

• The percentage of data that falls below a certain value

• The percentage of data that exceeds a certain value

• A measure that divides the data into four equal parts

• A measure that divides the data into ten equal parts

Which quartile is equivalent to the median of a data set?

• First quartile

• Second quartile

• Third quartile

• Fourth quartile

The interquartile range (IQR) measures:

• The difference between the maximum and minimum values

• The difference between the first and third quartiles

• The sum of the first and third quartiles

• The difference between the median and the mean

Given the data set: 3, 5, 7, 9, 11, what is the median (50th percentile)?

• 5

• 7

• 9

• 11

For the data set: 2, 4, 6, 8, 10, 12, what is the first quartile (Q1)?

• 2

• 3

• 4

• 6

For the data set: 2, 4, 6, 8, 10, 12, what is the third quartile (Q3)?

• 8

• 10

• 12

• 6

In a data set, the 90th percentile is:

• The value below which 90% of the data falls

• The value above which 90% of the data falls

• The median value

• The value that divides the data into nine equal parts

If the 75th percentile height of 50 Grade 10 students is 165 cm, this implies that:

• 75% of the students are taller than 165 cm

• 75% of the students are 165 cm or shorter

• Exactly 75 students are shorter than 165 cm

• 25% of the students are 165 cm or shorter
