Measures of Central Tendency
Mathematics Solutions from Chapter -1 - Measures of Central Tendency
This chapter explains the concept of arithmetic mean, combined mean and weighted mean. We will study the methods to calculate mode and median, along with the frequency curve. It also briefs on the quartiles and interquartile range.
Practice Other Topics from Measures of Central Tendency
This topic shows how to represent a cumulative frequency distribution graphically as a cumulative frequency curve, or an ogive of the less than type and of the more than type. It teaches how to obtain the median from the given data.
From this topic, we will try to understand the concept of mean. We will also learn how to find out the mean of ungrouped data. It also covers some examples to enhance our knowledge and gives its applications.
In this topic, we will learn about arithmetic mean of grouped data or a discrete frequency distribution. In a discrete frequency distribution, arithmetic mean may be computed using Direct method, Short-cut method, and Step-deviation method.
This topic discusses various methods of finding the mean of ungrouped data. It also gives us an idea about its applications in arranging data. We will also deal with some examples related to this concept.
The median is the middle value of any distribution of data given. We will learn to find the median for discrete and grouped data in this topic.
In this topic, we will study the concept of mean of ungrouped data. We will further learn how to find out the mode via some examples. This measure of central tendency proves to be a very interesting and important measure.
In this topic, you will learn about the computation of mode of a discrete frequency distribution and frequency distribution with class interval.
In this topic, we will learn how to divide given data into four equal parts. These parts are called quartiles. It further gives some formulas to find the lower quartile and the upper quartile when n is even or odd.
