A measure of the variation around the estimate of the mean.

The standard deviation is a statistic that lets you know how tightly all the subjects are clustered around the mean in a set of data. A single standard deviation away from the mean in either of the directions accounts for somewhere around 68 % of data. If two standard deviations are away from the mean, it accounts for around 95% of data. If three standard deviations are away it accounts for 99% of the data.

1) The total range of variation in the dataset is called RANGE.

3) A measure of the variation around the estimate of the mean is SEM (STANDARD ERROR OF THE MEAN).

4) The most common value observed (highest frequency) is MODE.

What is the measure of z? 3 27 y x z
Sholpan [36]

Answer: 3\sqrt{10}

Step-by-step explanation:

By the geometric mean theorem,

\frac{y}{3}=\frac{27}{y}\\y^{2}=81\\y=9

So, by the Pythagorean theorem,

3^{2}+9^{2}=z^{2}\\90=z^{2}\\z=\boxed{3\sqrt{10}}

Explain how you can tell, without computing, whether the quotient of 1/2 divided by 6 is greater than 1 or less than 1.
Gnesinka [82]
You already know that the quetioent of 1/2 divided by 6 would be more or less than one because, 1/2 is equal to 50% and 50% of 6 is 3. So, you would know how the answer would turn out.
