![]() The values given in the data set are added up together. The mean value for a given set of data is calculated in a two-step process: So, the mean of the data set 4, 5, 6, 3, and 7 is 5. In order to find the mean of 4, 5, 6, 3, and 7, first, we have to add the numbers and then divide the sum by the number of items.Ĥ + 5 + 6 + 3 + 7 = 25 i.e. The median is defined as the value present in the middle of a given set of data and the mode is the frequency with which a particular number occurs in a given set of data. The other two statistical methods used are median and mode to obtain a result for a given set of data. Mean = Sum of Observations/Total number of observations The formula denoting the mean of a given set of data is as follows: At least two numbers are needed in order to calculate the mean. To calculate the mean, you need a set of related numbers (or data set). The ‘mean’ or ‘arithmetic mean is the most commonly used form of average. This symbol appears on scientific calculators and in mathematical and statistical notations. The mathematical symbol or notation for the mean is ‘x-bar’. This is referred to as the total of all the values of data provided divided by the number of data values in total for any given set of data. The definition of a mean for a given set of data is the average calculated for a given set of numbers or data. ![]() It also measures the central tendency of data. It is also known as arithmetic mean or the average of a given set of data. ![]() The term ‘Mean’ is used constantly in the field of Statistics and is one of the basic methods used to obtain a result.
