Write the formula to calculate mean.
Answers
It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Answer:
Mean = Sum of All Data Points / Number of Data Points
Step-by-step explanation:
Mean is a point in a data set which is the average of all the data point we have in a set. It is basically arithmetic average of the data set and can be calculated by taking a sum of all the data points and then dividing it by the number of data points we have in data set. In statistics, mean is the most common method to measure the center of a data set. It’s a very basic yet important part of the statistical analysis of data. If we calculate the average value of the population set, then it is called the population mean. But sometimes what happens is that population data is very huge and we cannot perform analysis on that data set. So in that case, we take a sample out of it and take an average. That sample basically represents the population set and mean is called a sample mean. Mean value is the average value which will fall between the maximum and minimum value in data set but it will not be the number in the data set.
mean is a usual average
