## Mode – The Math

For a set of given observation, mode is that observation which occursmaximum number of times. 1. Find the mode of the given set of number 2, 2, 3, 5, 4, 3, 2, 3, 3, 5 Solution: Arranging the number with same values together, we get 2, 2, 2, 3, 3, 3, 3, 4, 5, 5 We …

## Median – The Math

Median of a group of observation is the value which lies inthe middle of the data (when arranged in an ascending or descending order) withhalf of the observations above it and the other half below it. ● When the number of observations (n) is odd. Then, median is (n + 1)/2 th observation. ● When …

## Construction of Pie Chart – The Math

Now we will discuss about the construction of pie chart or pie graph. Inbrief let us recall about, what is a pie chart? It is a circular graph which is used torepresent data. In this : ●Various observations of the data are represented by thesectors of the circle. ●The total angle formed at the centre …

## Data and Information – The Math

In this method, each number is represented by a string of symbols where each symbol is associated with a specific weight depending upon its positions. The total number of different symbols which are used in a particular number system is called …

## Decimal Number System – The Math

What is Decimal NumberSystem? Decimal number system is the most common example ofpositional notational number system and all the arithmetical calculationsundertaken by human being are carried out on the basis of this number system.In this system, the symbols used are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and the baseis 10. Thus …

## Line Graph – The Math

The data which changes over a period of time can bedisplayed through a line graph. In line graph: ● Points are plotted on thegraph related to two variables ● Points are joined by theline segments. How to Construct a Line Graph? Steps of construction of line graph: On a graph, draw two lines perpendicular to …

## Equivalence Relation on Set – The Math

Equivalencerelation on set is a relation which is reflexive, symmetric and transitive. A relationR, defined in a set A, is said to be an equivalence relation if and only if (i) R isreflexive, that is, aRa for all a ∈ A. (ii) R is symmetric, that is, aRb ⇒ bRa for all a, b ∈ …
