Answer

standard deviation

Explanation

Standard deviation is the measure of spread of data around the mean.

Mode is the most common value - which would be the mean in a normal-like distribution.

Median is the middle value when the data is ranked in ascending order (or descending even)

Skewness, is when the mode of the data falls behind the mean by a large margin.

An example is GDP, a few billionaires increase the number number and distort it, even though most people are of low or middle based income.

Answer:

<em>Probability ≈ 0.0833</em>

Step-by-step explanation:

Consider steps below;

Total Possible Outcomes - 9C6,\\\\9! / 6! ( 9 - 6 )!,\\1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 / ( 1 * 2 * 3 * 4 * 5 * 6)( 1 * 2 * 3 ),\\\\362,880 / 720 * 6 = Combinations - 84,\\\\

Number Of Outcomes - 7C6,\\\\7! / 6! ( 7 - 6 )!,\\1 * 2 * 3 * 4 * 5 * 6 *7/ ( 1 * 2 * 3 * 4 * 5 * 6 ) ( 1 ),\\\\Outcomes - 7

Conclusion ; Solution - 7 / 84 = ( About ) 0.0833\\Hope That Helps!

<em>Solution; Probability ≈ 0.0833</em>
