Question 28 (OR 2nd question) The following data indicates the marks of 53 students in Mathematics. Draw less than type ogive for the data above and hence find median To solve this, first we find cumulative frequency and then make a less than table βˆ‘β–’π‘“π‘– = 53 So, N = 53 ∴ 𝑁/2 = 53/2 = 26.5 We draw a line parallel to x-axis where Number of students = 26.5 Where the line intersects the curve at x-axis, it is the median ∴ Median marks = 64
