graphical representation of ogives by lower and upper class boundary

Summary - Two types of graphical representation of data are the histogram and the ogive. A histogram is a diagram which represents the class interval and frequency in the form of a rectangle. When the class intervals are unequal, each rectangle is constr..

Graphical representation is more informative than tables as it gives a visual representation of two quantities (e.g., speed vs. time) ..

(i) We plot the points with coordinates having abscissae as actual lower limits and ordinates as the cumulative frequencies, (70.5, 2), (60.5, 7), (50.5, 13), (40.5, 23), (30.5, 37), (20.5, 49), (10.5, 57), (0.5, 60) are the coordinates of the points. (ii) Join the points by a smooth cur..

(i) We can plot the ordered pairs in A x B by taking the first element along the X-axis and the second element along the Y-axis in the Cartesian plane. This diagram is called Lattice. Each ordered pair is marked by a point called the LATTICE point. A x B = {(3, 2), (3, 4), (3, 6), (5, 2), (5, 4), ..
