Question

Nia found the falling prices for short $25 $20 $19 $20 $18 $19 and $32 and $29 find the mean median and mode for the prices

Answer 1

Mean = $22.75

Median = $20

Mode = $19 and $20

Explanation:

Mean is the average. It's the numbers added together and then divided by the number of numbers.

`\displaystyle (\$25 +\$20 +\$19+ \$20+ \$18 +\$19 +\$32 +\$29)/(8)`

`\displaystyle (\$182)/(8)`

$22.75

Median is the number in the middle when the numbers are put in order from least to greatest.

$25, $20, $19, $20, $18, $19, $32, $29

$18, $19, $19, $20, $20, $25, $29, $32

---, $19, $19, $20, $20, $25, $29, ---

---, ---, $19, $20, $20, $25, ---, ---

---, ---, ---, $20, $20, ---, ---, ---

$20

Lastly, the mode is the number that appears most often. Both $19 and $20 show up twice. This gives us $19 and $20 as the mode.
