Rules of Addition and Subtraction of like Terms In this lesson we will learn, how to add and subtract like terms Like Terms In an algebraic expression, like terms are terms that have same variables with same exponents and only the numerical coefficients of like terms are different. The terms must have the same variables […]

Grouped data has been classified and a data class is group of data. Consider the marks obtain by 15 students in a history test as given below, 23, […]
Read More →Find Mode by Histogram In this tutorial, we will learn, how to find mode of a given observation with the help of a histogram. First we know about mode. What is mode? Definition: The mode of a data set is the value, occurring most frequently in set of observations. In other words, a data set having highest […]

Definition: The mode of a data set is the value, occurring most frequently in set of observations. In other words, a data set having highest frequency of observations is its mode. How to find […]
Read More →Range – Definition – Examples – Formula – Statistics Definition: In statistics and mathematics, range is defined as the difference between the highest and lowest value in a set of data. Range Formula The formula for the range is the highest(maximum)value minus lowest(minimum) value in a data set. Range = Highest value – Lowest value […]
