Normality Tests, Q-Q Plot & Histogram in ExcelA continuous distribution describes a variable that can take on any numeric value (for example, weight, age, or height).

Univariate descriptive statistics
Descriptive statistics provide information about the central location (central tendency), dispersion (variability or spread), and shape of the distribution.
Univariate plot
A univariate plot shows the data and summarizes its distribution.
Frequency distribution
A frequency distribution reduces a large amount of data into a more easily understandable form.
Normality
Normality is the assumption that the underlying random variable is normally distributed, or approximately so.
Inferences about distribution parameters
Inferences about the parameters of a distribution are made using a random sample of data drawn from the population of interest.
