Question

Im so confused what is this?

Answer 1

the series is always arranged in ascending order:

3 3 6 6 8 9 10 11 14 14 14 19 22 31

smallest value :3

Q1 : 1/4 or 25%

14/4 = 3.5; the next higher integer is 4. The first quartile Q1 is rank 4, i.e. value 6.

median: separates the series into 2 series of smaller values

14 values, even series

14/2 =7

half sum of 7th and 8th values (10+11)/2=10.5

median:10.5 (in the even series, the median is not always shown in the given series)

Q3: 3/4 or 75%.

(14*3)/4=10.5; the next higher integer is 11. The third quartile Q3 is at rank 11 or the value 14

maximum: the highest value, i.e. 31

Answer 2

min = 3

Q1 = 6

Median = 10.5

Q3 = 14

Max = 31

Explanation:

The minimum value of a data set is the smallest value = 3

The maximum value is the largest value = 31

The median is the middle value after arranging the data from smallest to large.

Q1: the first quartile is the value of the data under 25% after arranging the data in increasing order.

Q3: The upper quartile is the value of the data under 75% after arranging the data in increasing order.
