Statistics Concepts – Mean, Median, Mode and Solved Examples

However, the method to calculate the arithmetic mean can vary based on the frequency of each variable in the data set — simple average equally weighted or weighted average. The formula for the arithmetic mean for equally weighted variables can be derived by summing up all the variables in the data set and then divide the result by the number of variables. Mathematically, it is represented as,. In case of unequally weighted variables, the formula for the arithmetic mean can be derived by summing up the products of each variable and its frequency and then the result is divided by the sum of the frequencies. Let us take an example of a batsman who scored the following runs in his last 10 innings during last one year: 45, 65, 7, 10, 43, 35, 25, 17, 78,

There are three main types of average problems commonly encountered in school algebra: Average Arithmetic Mean , Weighted Average and Average Speed. One type of average problems involves the weighted average - which is the average of two or more terms that do not all have the same number of members. To find the weighted term, multiply each term by its weighting factor, which is the number of times each term occurs. A class of 25 students took a science test.

Unlike range and quartiles, the variance combines all the values in a data set to produce a measure of spread. The variance symbolized by S 2 and standard deviation the square root of the variance, symbolized by S are the most commonly used measures of spread. We know that variance is a measure of how spread out a data set is. It is calculated as the average squared deviation of each number from the mean of a data set.

In this post, we will be discussing mean, median, mode concepts and their solved examples which is a frequently asked topic in XAT and SNAP examination. We will start our discussion with basic concepts of statistics followed by some examples that will help you get a better understanding of the concept. The short tricks to solve some particular questions are discussed during the solution of the question. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. If no number in the list is repeated, then there is no mode for the list.
