Which measure of central tendency is important for using higher statistics ?
Answer: A
The measure important for higher statistics is the mean.
The arithmetic mean uses every value in the data and can be handled algebraically, so it is the basis of the standard deviation, variance, correlation, regression and tests of significance such as the t test. It is also the most stable measure from sample to sample.
The mode and median do not use all the values and are not suited to algebraic treatment, and the harmonic mean is used only for special cases such as averaging rates.
