RS Aggarwal Class 10 Solutions chapter 9 Mean, Median, and Mode

The three most common and very important ways to measure central tendency are the mean, the median, and the mode. All three of these methods take a set of data and find some kind of average from it. The coefficients of these methods tell us how important or unimportant that set of data is. Mean, median, and mode are the most important parts of statistics because they are the most basic parts. Even though we only learn about it as a chapter in our math books until 10th grade, statistics is also a separate field. Now, according to the RS Aggarwal book, let’s look at mean, median, and mode (class 10).

Mean

The average value of a set of numbers is its mean value, which can be found by using the following formula:

• X̅ = ∑xn
• X̅ = mean value
• ∑x = sum of all values
• n = number of occurrences

To find the average value of a set of numbers, we can use the direct method, the assumed mean method, or the step-deviation method.

Mode

The observation or value in a set of data that shows up most often is called the “mode.” When trying to find the mode, use the following formula:

• Mode = l+(f1−f02f1−f0−f2)×h
• Where, L = the lowest point in the modal class h = the class interval size 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 is the value of the data that is in the middle of the set. The formula for finding the median is as follows.

• Median = (n+12)th
• occurrence where n = number of occurrences

The basic formulas to find the mean, median, and mode are different for different types of data sets, such as individual, discrete, and continuous series.
