Variability is the measure of the variation of a data set from the center. The mean and the median are the qualities that measure the center of a distribution.

For the first option, if more data is clustered around the median, (the measure of center), then the distribution has less variability than when less data is clustered around the median. Therefore, the first answer option is not correct because if more data is clustered around the median in the shaded plants set, then the shaded plant set will have less variability.

For the second option, the range is a measure of variability which measures the spread of the data set from the least value to the greatest value, but it does not take into account the variability of the other data values of the data set. Thus the range is regarded as a weak measure of variability and is not used when other measures of variability are available. Therefore, the second option is not correct.

For the third option, the inter-quartile range (IQR) is a better measure of variability than the range because it takes into account more data points than the range. Now, because, the f<span>ull sun plants set has a greater IQR, this shows that they have greater variability. Therefore, the third option is the correct answer.

For the fourth option, the median is not a measure of variability. Thus, that a data set has a greater median than another data set does not mean that the data set would have a greater variability. Therefore, the fourth option is not the correct answer.</span>

coldgirl [10]

Answer:

431.775 ft

Step-by-step explanation:

So basically we should first find the area of the rectangles which is  28 ft * 15 ft, which you get 420. Next for the semicircle, the diameter is 15 but we need the radius so you divide that by 2 to get 7.5 as the radius. Then u multiply 7.5 * π, or 3.14 to get 23.55. But since its a semicircle, or half a circle we divide 23.55 by 2 which is 11.775. Then we just add the results which is 420 ft and 11.755 ft to get a total area of 431.775 ft.

Below is a map of Yellowstone Park. The scale for the map is 1cm = 25 miles.
eimsori [14]

Answer:

Option D. 75 miles

Step-by-step explanation:

Looking at the Yellowstone Park map we can see that Mrs. Folwer went from Old Faitful to the Canyon by covering a straight line of 3cm.

This tells us that we do not need extra calculations to find the distance covered on the map. We also know that the map scale is given as 1cm=25miles. So similarly we do not need to do extra ratio conversions.

Thus we know that if 1cm=25miles and she covered 3cm on the map, we can just multiply covered distance with the equivalency of cm in miles as follow:

Distance=(3cm)  (25 miles)=75miles

Thus Mrs. Folwer's actual distance from Old Faithful to Canyon in Miles is 75 miles. (<u>which is given in Option D</u>.)
