Draw a histogram of the following data, Class-interval 25 - 35 35 - 45 45 - 55 55 - 65 65 - 75 Frequency 10 15 25 20 5

According to the data provided in the question, the histogram graph is given below-

Draw the histogram of the following; I.Q score 80 - 90 90 - 100 100 - 110 110 - 120 120 - 130 130 - 140 no. of students 6 9 ` 16 13 4 2

A histogram is the graphical representation of data where data is grouped into continuous number ranges and each range corresponds to a vertical bar. The horizontal axis displays the number range. The vertical axis (frequency) represents the amount of data that is present in each range. According to the data provided in the question, the histogram graph is given below-

Draw the frequency polygon for the following frequency distribution: Class - interval Frequency class- interval Frequency 0 - 10 5 40 - 50 10 10 - 20 7 50 - 69 11 20 - 30 7 60 - 70 12 30 - 40 8 70 - 80 8

Here, the intervals are already overlapping (that is, the distribution is continuous) Class Interval Frequency Class Marks 0 - 10 5 5 10 - 20 7 15 20 - 30 7 25 30 - 40 8 35 40 - 50 10 45 50 - 60 11 55 60 - 70 12 65 70 - 80 8 75 According to the data provided in the question, the Frequency polygon graph is given below-

Draw the histogram and frequency polygon from the following data: Class-Interval 20 - 25 25 - 30 30 - 35 35 - 40 40 - 45 45 - 50 Frequency 24 30 52 46 28 10

According to the data provided in the question, the histogram graph is given below- class interval 20 - 25 25 - 30 30 - 35 35 - 40 40 - 45 45 - 50 class marks 20 + 25 2 = 22 . 5 27 . 5 32 . 53 37 . 5 42 . 5 47 . 5 frequency 24 30 52 46 28 10
