Mean, Median, Mode - Class 10 RS Aggarwal Solutions

Mean, median and mode are the three most common and very important measures of central tendency. In their essence, all three of them take out one or another kind of average from a given set of data, and their coefficients give us information about how significant or insignificant that set of data is. Mean, median and mode are important components of statistics as they are the basic components of statistics. While we study it as a mere chapter in our maths textbooks up till class 10, do understand that statistics is also a discipline in itself. Let’s now take a look at mean, median mode (class 10) as per the RS Aggarwal book.


Mean

The mean value of a set of data is the average value of that data, and it is measured by the following formula:

\[\bar{x}\] = \[\frac{\sum x}{n}\]


Where,

\[\bar{x}\] = mean value

\[\sum x\] = sum of all values

n = number of occurrences

We may use the direct method, assumed mean method or the step-deviation method to find the mean value of a set of data. 

 

Mode

Mode refers to the observation or value in a set of data which occurs the most frequently in that set. The following is the formula to be used when trying to find the mode:

Mode = \[l+(\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}}) \times h\]


Where,

L = lower limit of the modal class

h = size of the class interval

f1= frequency of the modal class

f0= frequency of the class above the modal class

f2= frequency of the class below the modal class

 

Median

The median gives us the value of the data which lies middle-most in the set of data, and the formula for it is as follows.

Median = \[(\frac{n+1}{2})^{th}\] occurrence where n = number of occurrences


occurrence where n = number of occurrences

Different kinds of data sets (i.e. individual, discrete and continuous series) have their own variations of the basic formulae to find the mean, median and mode.
