What is the arithmetic mean of a data set is the measure of center?

It is one measure - not the only one - of a "central tendency". It is the same as the "average". To calculate the average, just add all the numbers, and divide the result by the amount of numbers.

What statement about the data is true 724 727 996 712 725 704 730 710 Both the median and mode are appropriate measures of center. The median is the only appropriate measure of center. The mean media?
There is no mode so it is not a measure of anything! Te data set contains an outlier: 996 and so the median is a better measure of the centre than the mean.
Which measure of varartion is preferred when the mean is used as the measure of center?
standard deviation
What would the 5th Arithmetic mean be equal to if 8 Arithmetic Means are placed between 2 and 17?
It is not possible to place 8 arithmetic means between two numbers since they can have only one arithmetic mean not eight! The one-and-only arithmetic mean of 2 and 17 is (2+17)/2 = 9.5
The measure of location that is the most likely to be influenced by extreme values in the data set is the range?
mean
What is the Formula for arithmetic mean?
The arithmetic mean is the average of all values. Add all of the values together and divide by the number of values.Suppose you want to find the arithmetic mean of n numbers, which are x1, x2, x3, ... , xn.Then the arithmetic mean = (x1 + x2 + x3 + ... + xn)/n , that is, the sum of all the values whose mean you want, divided by the number of values.Example: values 2, 8, 11The sum of the three is 21, divided by three gives the mean = 7
Why is mean a measure of the center of the data?
mean does not mean the center of the data
Why is the mean a measure of the center of the data?
mean does not mean the center of the data
Does the coefficient of variation measure variability in a data set relative to the size of the arithmetic mean?
Yes.
Can the arithmetic mean be converted into the geometric mean without having the original data?
Let me clarify. I only have the arithmetic mean. I don't have the data from which it was determined.
The number of times a particular item appears in a data set?
arithmetic mean
When is finding the average not useful?
There is no meaningful average wen data are categorical (qualitative). Also, the arithmetic mean is not a good measure of central tendency when the data distribution is skewed.
Which numerical measure of center is most affected by extremely high or low numeric data?
Mean.
What is the data set id the sum of the data divided by the number of pieces of data?
It is the [arithmetic] mean.
What is the sum of the numbers in a set of data divided by the number of pieces of data?
The mean. Strictly, the arithmetic mean.
What is an arithmetic mean?
An arithmetic mean is a measure of central tendency of a set of values computed by dividing the sum of the values by the number of values.
Why do we need the quadratic mean How is it better than the average mean?
The quadratic mean is a measure of the spread of values about their arithmetic mean. By definition, the arithmetic mean of the differences will be zero and so adds no information. Another measure is required and that is the quadratic mean.
What measure of center best represents data?
The answer depends on the type of data. The mean or median are useless if the data are qualitative (categoric): only the mode is any use. The median is better than the mean is the data are very skewed.
