What does variability mean? Can you give an example?

answer: data points in a statistical distribution or data set diverge from the average value as well as the extent to which these data points differ from each other

Step-by-step explanation: An example is like an outlier. It you have data that reads 11,13,15,17,and 60. The one that is different would be 60. So, variability is when you have data but one point is very different than the others.

answer:

Variability refers to how spread out a group of data is

Step-by-step explanation:

The terms variability, spread, and dispersion are synonyms, and refer to how spread out a distribution is. a graph is a good example

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
