Question

Find the mean, median, mode, range, and standard deviation of the data set that is obtained after multiplying each value by the given constant. Round to the nearest tenth, if necessary. If there is no mode, write none.

1, 5, 4, 2, 1, 3, 6, 2, 5, 1; x6.5

Answer 1

Explanation:

First, organize the numbers; 1,1,1,2,2,3,4,5,5,6. The median is the middle number, in this case, 2 and 3 are in the middle. You'd add 2+3 which equals 5, then divide by 2 to get 2.5. The median is 2.5, to find the mode you need to see how many times one number appears. The mode is 1, the range is the largest number minus the smallest number. The range is 5, to find the mean you add all numbers up, then divide by how many numbers there are. All the numbers added up are 30, now divide that by 10 to get 3. The mean is 3. The standard deviation is 1.7 x 6.5 = 20.8

I'm only an algebra student so I may not be entirely correct.
