There are infinitely many options. 1,2,3,4,5,6,63
All that you need to ensure the result is that you have 7 different numbers that sum to 7*12 = 84.

Is the mean equal to the median in a data set consisting of 1000 values that are all different?
If a data set consists of 1000 different values can the mean and the median be the same
Why it is useful to fiNd the meaN mediaN aNd mode of a set of data?
when there are extreme values in the data
What is mean data?
Mean data are observations whose values are equal to the mean of the data set. By default it is the arithmetic mean but it could be the geometric or harmonic mean - if those measures are more appropriate.
A set of 1000 values has a normal distribution the mean of the data is 120 and the standard deviation is 20 how many values are within one standard deviaiton from the mean?
The Empirical Rule states that 68% of the data falls within 1 standard deviation from the mean. Since 1000 data values are given, take .68*1000 and you have 680 values are within 1 standard deviation from the mean.
What does data range mean?
Data Range is the values of the data from the minimum to the maximum that you are sampling. For plotting purposes(such as in EXCEL spreadsheet), it is the minimum and Maximum range of the values of X-Axis and Y-Axis.
What is mean by distinct in oracle?
the distinct in oracle is there is no repetition of data in a query
What is the sum of the data divided by the number of data values?
It is the mean average of number of collected data values.
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
What is the arithmetic mean?
The arithmetic mean is calculated by adding together the values and dividing by how many values there are. This is distinct from the geometric mean which is calculated as the nth root of the product of the values where n is the number of values multiplied together.
Which measure of central tendency equals the sum of the data values in a set divided by the number of data values?
mean
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.
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.
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
