Answer:

The median is 1.84

Step-by-step explanation:

To find the median we need to first put the amounts in ascending order.

$1.61, $1.75, $1.79, $1.84, $1.96, $2.09, $2.11

To determine the median we now select the middle most term, which is $1.84.

Median = $1.84

Difference = $0.34

Order the Data:

$1.61

$1.75

$1.79

$1.84

$1.96

$2.09

$2.11

Median - The middle value.

Cross of 1 from each side till you only have 1 left. If you have two left, add them together and divide by 2.

$1.61, $1.75, $1.79, $1.84, $1.96, $2.09, $2.11

$1.75, $1.79, $1.84, $1.96, $2.09, $2.11

$1.75, $1.79, $1.84, $1.96, $2.09

$1.79, $1.84, $1.96, $2.09

$1.79, $1.84, $1.96

$1.84, $1.96

$1.84

Quartiles - They are found at position 1/4 and 3/4 of the total number of elements. Or 1/2 the median's position or 1/2 the median's position + the median's position.

1/4

Median's position is 4

1/2 = 2

Position 2 =  $1.75

3/4

4 + 2 = 6

Position 6 = $2.09

$2.09-$1.75 = $0.34
