 Hello and welcome to the session. In this session we will discuss a question which says that make a void plot for the set of data which shows percentage of students in mathematics and the percentages are given as 85 and 88. Also write one or two sentences that analyze the data. Now before starting the solution of this question, you should know how to solve it. And that is, rank net with the graph that shows the frequency of the data along a number line. And it is best to use a line plot when comparing fewer than 13 numbers and it is a quick simple way to organize the data. Now let us discuss the steps to make a number line plot. Now once a data is collected, it is then the time to make a line plot. And the first step which we will follow is determine the scale to be used. Then in the second step, draw a horizontal line across the paper. Then in the next step, write the line into equal parts that will go into your scale. In the next step, list the data and place a star with the correct number. For each of the observations, a number is repeated when place the star over the other. Now this result will work out as a key idea by solving out the given question. And now we will start with the solution. Now in this question, we are given a data of percentages of students. And math says in order to make its line plot, we will follow the steps which we have discussed in the key idea. Now in the first step, we have to determine the scale. And here in the given data, we can see that the values of the percentages range from 75 to 95. So in the first step as the values range from 75 to 95, we will take, it means we will take a distance of 5 between two numbers. That is, we will take 75, 80, 85, 90 and so on. We will draw a horizontal line. So here we have drawn a horizontal line. Then in the next step, we will break the line into equal parts. We will take a difference of 5 between two numbers on a number line. As here we have taken 75, 80, 85, 90 and 95. The difference between the two numbers, that is the difference between two consecutive numbers is 5. Now here we have taken the numbers from 75 to 95 as the values in the given data range from 75 to 95. We will arrange the given data in order. So here we have arranged the given data in order. We will arrange this given data on the number 9 observation. We will put a star sign. Now here you can see that 75 is coming two times in the data. So as 75 is coming two times, so we will put for 75. Then 79 is coming once. Now here this is the line for 75. And the next line is for 76. Then 77, 78 and this is the line for 79. Now 79 is coming once. So we will put only one star for 79. Then 80 is coming twice. For 80 we will put coming twice. For 82 also we will put. Then 83 is coming once. So for 83 we will put one star. Then 85 is coming sixth. So for 85 we will put the stars for the other observations also. Now here from this number line plot we have plotted all the observations. Now here from this number line plot you can observe that there are two students who have scored 95 percent in mathematics test and three students have scored 90 percent in mathematics test and so on. So we have marked the entire percentage on the number line. We are getting the required graph. Now from the graph we can see that most of the data is concentrated between 80 and 90 and 85 is the centre of the data. So from the number line plot we analyze that the most of the data is concentrated between 90 is the centre of the data. This is the solution of the given question and that's all for this session. Hope you all have enjoyed the session.
