Answer:
Step-by-step explanation:
Concept:
In mathematics, the central value of a set of data is expressed as the average of a list of data.It is defined mathematically as the ratio of the total number of data points to the number of units in the list.In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data.The average of 2, 3, and 4 is, for instance, (2+3+4)/3 = 9/3 = 3.The centre value of 2, 3, and 4 in this instance is 3, thus.Finding the mean value of a bunch of numbers is the definition of average.
Definition:
The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.The average formula has numerous practical uses.If we were asked to determine the average male height in India or the average age of the men and women in a group, we would add up all the data and divide it by the total number of data points.
Formula:
Average = Sum of Values/Number of Values
Symbol:
The mean of the variables that are represented by x is essentially what the average is. The symbol "μ" is also used to represent it.
Solution:
Average =(15+14+21+30)/4
=80/4
=20
