Our text explains that we are able to calculate where the center of a frequency is distributed using three measures that are commonly used: mode, median, and mean (Field,2018). The mode is the score that occurs the most frequently in the data set; the median is the middle score when scores are ranked in order of magnitude; the mean is the measure of central tendency that is also known as the average score (Field, 2018). I have attached a histogram chart of the Album Sales that were measured on SPSS: The x-axis represents the Album Sales (in the thousands) and the y-axis is labeled as the frequency (the number of times the corresponding x value sold in the thousands). Here we take a more detailed look at the x-axis, which will help measure the central tendencies:

Attached we see the variability measures:
The statistical analysis to the right of the graph shows that there is in fact a standard deviation of
80.699 with a variance of 6512.322 and a range of 350.
Our text defines a standard deviation as an estimate of the average variability (spread) of a set of
data measured in the same units of measurement as the original data; it is the square root of the
variance (Field, 2018). This means the standard deviation is the average of a data set that is given
to us, nothing more and nothing less than what is given to us, it must be measured in the same
