Which of the following is a difference between a mean and a median? group of answer choices a median is not meaningful for ratio data; a mean is meaningful to ratio data. a mean is an observation that occurs most frequently; a median is the average of all observations. a median is not affected by outliers; a mean is affected by outliers. a mean divides the data half above it and half below it; a median does not.

Mean is the average and median divides data into two equal parts.

Step-by-step explanation:

We have to state the difference between mean and median.

Formula:

Mean

Median = The value that divides data into two equal parts.

If there are n number of observations and the data is arranged in ascending or descendin order, then,

Median =

Basically, mean is the average of the data and median is the value that divides the data into two equal parts. Mean does not divide the data into two halves like the median.

A mean is affected by the outliers where as median being a position based description is not affected by the outlier.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: 100
