Answer 4

False. Consider the data set { 1, 2, 3, 4}. The median is not a member of the set.

Answer 5

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.

Answer 6

false

Answer 7

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

Answer 8

The median is the middle number of the data once the set has been put in order. If there are 2 middle numbers, you find the average of those numbers. The average is not always one of the listed data points.

Examples:
1, 4, 7, 2, 8, 4, 9, 3-----> 1,2,3, 4,4,7,8,9. There are 8 numbers. The middle number is the average of 4 & 4. The median is 4 because 4 + 4 is 8 & 8/2 = 4. 4 is one of the listed data points

1,4,2,8,3,9,2,7--------> 1,2,2,3,4,7,8,9. There are 8 numbers. The middle number is the average of 3 & 4. (3.5) 3.5 is not one of the listed data points.

Answer 9

so false?

Answer 10

Yes, False:

Coz the median is the middle number in a group of data
if there is no "middle" number ad the two middle numbers together and then divide by 2
example:
1,2,3,4
2+3=5
5 divided by 2 is equal to 2.5
2.5 is your median

Sometimes, The median of a data set is one of the data values.
