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.

How mean of a data set is always one of the data points in a set of data. Explain?
The mean of a set of data is the sum of all those data values, divided by the numbers of values in the set. For instance, if we had 1, 3 and 5, the mean would be (1+3+5)/3 = 3. The mean doesn't always have to be one of the data points in the set. For instance, if we had the data 1, 6, 7, 7, 8. The mean would be (1+6+7+7+8)/5 = 5.8, even though 5.8 isn't one of the values in the set.

What is A set of data values called where there are more data values above the Mean?
skewed
The sum of the values of a data set divided by the number of values?
Will gve the mean average of the data
Which measure of central tendency equals the sum of the data values in a set divided by the number of data values?
mean
A single, extremely large value can affect the median more than the mean?
A single, extremely large value can affect the median more than the mean because One-half of all the data values will fall above the mode, and one-half will fall below the mode. In a data set, the mode will always be unique. The range and midrange are both measures of variation.
What is the arithmetic mean of the absolute values of the deviations of the individual values from the mean in a data set?
It is the mean absolute deviation.
The sum of the data values in a set divided by the number of values in the set?
Mean
What percentage of data values of a normal distribution will fall within one standard deviation below the mean?
34.1% of the data values fall between (mean-1sd) and the mean.
How do you find the mean of the data?
Th find the mean of a data set, you add up all the values in the data set and divide this sum by the number of data values. For example, the mean for the data set 2, 5, 6, and 7 is given as 2 plus 5 plus 6 plus 7, which is 20. You divide this sum by number of values in the data set, which is 4 to get 5 as the mean.
Does the mean have to be one of the data values?
Not all the time
What is the average of the values called in a data set?
