Why is the standard deviation preferable to the range as a measure of variation? select the correct answer below.

lesya692 [45]

I believe the answer is A, the standard deviation is preferable to the range as a measure of variation because the standard deviation takes into account all of the observations, whereas the range considers only the largest and the smallest. Range gives an overall spread of data from the lowest to the largest and thus can be influenced by anomalies, standard deviation on the other hand, takes into account the variable data/spread about the mean and allows for statistical use so inferences can be made.<span />

The data below show the weights, in pounds, of a group of professional football players.

Answer:

The Mean Absolute Deviation is 11

Step-by-step explanation:

Given:

325, 310, 289, 288, 285, 285, 285, 280, 280 and 273

Mean = 290

Required:

Calculate the Mean Absolute Deviation

Provided that we have the value of the mean to be 290 from the question; the following steps will calculate the Mean Absolute Deviation

Step 1: Subtract the mean weight from each weight

325 - 290 = 35

310 - 290 = 20

289 - 290 = -1

288 - 290 = -2

285 - 290 = -5

280 - 290 = -10

273 - 290 = -17

Step 2: Calculate the absolute value of the each results above

|35| = 35

|20| = 20

|-1| = 1

|-2| = 2

|-5| = 5

|-10| = 10

|-17| = 17

Step 3: Calculate the mean of the data above

Mean Absolute Value = $\frac{35 + 20 + 1 + 2 + 5 + 5 + 5 + 10 + 10 + 17}{10}$

Mean Absolute Value = $\frac{110}{10}$

Mean Absolute Value = 11

Hence, the Mean Absolute Deviation is 11

Find the midpoint of the line segment with end coordinates of:

Kaylis [27]

Answer:

Step-by-step explanation:

The Midpoint formula is

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$ where the x's and y's come from the coordinates of the endpoints. Filling in:

$M=(\frac{-2+(-1)}{2},\frac{-4+(-5)}{2})=(\frac{-3}{2},\frac{-9}{2})=(-1.5,-4.5)$
