Detailed explanation-1: -The distribution of a variable describes the pattern of variation of these values. The distribution of a variable tells us what values the variable takes and how often it takes these values. We can summarize a variable’s distribution with a frequency table or a relative frequency table.
Detailed explanation-2: -A continuous variable is a variable whose value is obtained by measuring, i.e., one which can take on an uncountable set of values. For example, a variable over a non-empty range of the real numbers is continuous, if it can take on any value in that range.
Detailed explanation-3: -Numeric variables A numeric variable (also called quantitative variable) is a quantifiable characteristic whose values are numbers (except numbers which are codes standing up for categories). Numeric variables may be either continuous or discrete.
Detailed explanation-4: -The response variable is the variable whose value can be explained by the value of the explanatory or predictor variable.
