Further, for better understanding the idea of the tally chart, examples have been solved for students. We understood the importance and benefits of adopting a tally mark chart. Then we explained how a tally mark chart could be prepared and read. We learnt the definition of the tally mark and then the counting of the tally mark. In this article, we have done a detailed study of the tally chart. The height of the students in cm from grade \(8\) is listed below: So the tally mark to show the total number of students is \(=20\) tally marks. Including you, your class strength is \(20\). One of your classmates got \(5\) marks, so you make one tally mark next to it.
Four of your classmates got \(2\) marks, so you make four tally marks next to it. Second is the number of students getting \(2\) marks.One of your classmates has got \(1\) mark, so you draw one tally mark in front of it. First is the number of students getting \(1\) mark.To look through this chart, you need to count the tally marks to find the number of students. So using tally marks becomes easier for you to record the data. Recording it using numbers every time, you have to erase the previous data and write the new one. The below example helps us understand the concept in a better way.Įxample: Let us assume you decided to make a tally chart to show marks of your classmates out of \(5\). This is how the tally marks become beneficial for finding the frequencies of the data set, particularly for ungrouped raw data. Thus, the table obtained is the required frequency distribution table for the given data. Then by counting the tally marks, we can write down the corresponding frequencies. In this way, we have to pass over the list only once. In this case, we have to add a tally mark for every different observation or class interval. This complication can be minimized by using the tally marks. Also, going back to the list repeatedly to cross-check the entire list becomes time-consuming. It is difficult to count all the occurrences and enter the data as there are chances of mistakes. We have options to make an individual observation or class intervals. Benefits of Using Tally MarksĪssume that we are given raw data or random values to formulate a frequency distribution. A group of tally marks showing data information in a table produce a tally chart.Ī tally chart is shown below consists of tally marks for the numbers counting from \(1\) to \(10\). Tally marks on graphs are a quick way to track numbers in groups of five. It helps us in arranging the data in a clear view. In statistics, a graphical representation of the data uses a tally mark chart. Two sets of five lines representing count \(10\).Set of five lines and four single vertical lines representing count \(9\).Set of five lines and three single vertical lines representing count \(8\).Set of five lines and two single vertical lines representing count \(7\).Set of five lines and a single vertical line representing count \(6\).Four vertical lines and a line drawn across four vertical lines representing count \(5\).
Four vertical lines representing count \(4\).Three vertical lines representing count \(3\).Two vertical lines representing count \(2\).One vertical line representing count \(1\).
