Question

Kelly rolled scores of 254, 202, 284, 269, 151, 258 and 202 in a recent tournament. What was the mean, median and mode of her scores?

Answer 1

See below!

Explanation:

Data:

254, 202, 284, 269, 151, 258, 202

Mean:

• The sum of data divided by the number of data is called mean.

Mean of the data:

`\displaystyle Mean= (Sum \ of \ data)/(number \ of \ data) \\\\Mean = (254+202+284+269+151+258+202)/(7) \\\\Mean=(1620)/(7) \\\\\boxed{Mean = 231.4}`

Median:

• The middle value of the data is median.

Median of data:

Arrange the data in increasing order.

151, 202, 202, 254, 258, 269, 284

The middle value = 254

So,

Median = 254

Mode:

• The frequently occurring value in the data is known as mode.

Mode in data:

The mode, here, is 202. (occurring 2 times.)

So,

Mode = 2

`\rule[225]{225}{2}`
