Question

Determine whether each statement is true or false. Explain.

1. The median of a data set is always one of the data values.

2. The number of permutations of two items from a data set is
always two times the number of combinations when taking two
objects at a time from the same data set. .

3. In large data sets (1,000 or more values), the mean is always one
of the data values.

Answer 1

Can you check see if i am right (below)

Answer 2

1.) TRUE a set of numbers (they have to be in order) [1,1,2,3,5,6,6,9,11,11,12] the median is the one in the middle(if it is between two number then find the distance between the 2 numbers)
[1,1,2,3,5,6,6,9,11,11,12] the median is 6,but if I add a 4 [1,1,2,3,4,5,6,6,9,11,11,12] the median would be 5.5 because the middle number is between 5 and 6

2.) FALSE y= x! / (x-y)!

3.) FALSE the mean is all the numbers added together then divided by the number of values there are (even if there are more than 1000 you could have a whole bunch of outliers making it a number you don;t have in your data
