Is median always part of the data set?
yes* * * * *No. If you have a small, even number of observations, the median is the average of the two middle values. This will usually NOT be part of the data set.
Which measure of central tendency is always part of any data set?
mean
Why will a set of data not always have a mode?
A set of data will not always have a mode because some data sets will not have a number that occurs more than once.
Will a set of data always have a mode in math?
No.
For a given data set the mean and median are always nearly equal?
No.

Part of a set of data as a percent of the whole set?
Circle Graph!
Is the range always part of the data set?
No. For example, consider a group of people whose height ranges from 1.5 metres to 2.0 metres. The range for this data set is 2.0-1.5 = 0.5 metres but there is no one in the group whose height is 0.5 m.
Will a set of data always have a mode?
No, because sometimes sets of data can have different numbers and other sets of data can have modes in them.
Is it true that in large data sets the mean is always one of the data values?
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
What is always a part of the scientific method controlled experiments or data collection?
