Question

Find the mean, mode(s), and median for the following set: 90, 92, 94, 91, 90, 94, 95, 98

Answer 1

Answer:

mean = 93

mode(s) = 90 and 94

median = 93

Step-by-step explanation:

Mean --> average value

$\sf{mean = \frac{90 + 92 + 94 + 91 + 90 + 94 + 95 + 98}{8} }$

$\sf{mean = \frac{744}{8} }$

$\bf{mean = 93}$

.

Mode(s) --> the most frequently occurring value

• 90 = 2
• 91 = 1
• 92 = 1
• 94 = 2
• 95 = 1
• 98 = 1

mode(s) = 90 and 94

.

Median --> middle value

sort from smallest

90, 90, 91, 92, 94, 94, 95, 98

median :

$\sf{median = \frac{92 + 94}{2} }$

$\sf{median = \frac{186}{2} }$

$\bf{median = 93}$

Answer 2

90 and 94 wold be the answer because if you put it in order it’s the only two that reappears
