Arithmetic mean in the most common and easily understood measure of central tendency. We can define mean as the value obtained by dividing the sum of measurements with the number of measurements contained in the data set and is denoted by the symbol $\barx$.
The distribution above shows strong signs of a normal distribution. The distribution above shows signs of a normal distribution but there is a trend for late night shopping. Students should investigate the idea of spread and how it is represented mathematically.
Any normal probability distribution can be converted into a standard normal probability distribution by subtracting the mean from each observation and dividing this.
The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others.
The arithmetic mean of a variable, often called the average, is computed by adding up all the values and dividing by the total number of values. The population mean is represented by the greek letter μ (mu). The sample mean is usually the best, unbiased estimate of the population mean.

The log-normal distribution is the probability distribution of a random variable whose logarithm follows a normal distribution.
Meaning of standard deviation: the best and most important measure of dispersion is standard deviation which was first worked out by karl pearson (1833). It is the positive square root of mean of deviations of individual values of a data series from the arithmetic mean of the series.
The goal of calculating a z - score is to relate a particular normal distribution to the standard normal distribution. The standard normal distribution has been well-studied, and there are tables that provide areas underneath the curve, which we can then use for applications.
