How to Find Median Value of Odd and Even Set of Data In this lesson we will learn how to calculate the median of a data set, when data set has odd and even numbers or observations. To learn the median of a data set, first we should understand what is median. (You can learn […]
Read More →Frequency Polygon A frequency polygon is very similar to a histogram and represents the graphical form of data. A frequency polygon is used to show a cumulative frequency distribution or compare to sets of data. In a frequency polygon the number of observations is marked at the the midpoint […]
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 […]
Read More →Arithmetic Mean Definition: The sum of the numerical values of each and every observation, that is divided by the total number of observations is equal to “Arithmetic Mean”. Arithmetic Mean is also called average or mean. The Arithmetic Mean or mean or average is defined as, Symbol: X = (𝚺xi)/n X = Mean […]
Read More →Mean Value – Word problems In this lesson we will learn about mean. We will also learn how to find mean of given data and solve word problems on mean. How to calculate mean Example: (1)What is the mean of 1, 2, 5, and 4. Solution : Mean = Sum of observations/Number of observations the numbers […]
Read More →Mode – Definition – Examples In this tutorial, we shall learn about mode and how to find mode of a given observation. 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 […]
