Exercise 14.4 Statistics
Solution :
The curve is a less than type graph the data changes to
X – axis – upper limit 1 cm = 50 units
Y – axis – less than c.f. 1 cm = 5 units
Solution :
Upper limits of the classes and less than cumulative frequencies. Therefore required points are (38, 0), (40, 3), (42, 5), (44, 9), (46, 14), (48, 28), (50, 32) and (52, 35)
X – axis – upper limits 1 cm = 2 units
Y – axis – less than c.f. 1 cm = 4 units
Number of observations = 35
N÷2 = 35÷2 = 17.5
The X – coordinate of the point is the required median.
From graph, median = 46.5
Solution :
The data is to be changed to more than frequency distribution type.
Graph is plotted by taking the lower limits on the X- axis and respective of Y- axis.
X – axis 1 cm = 5 units
Y- axis 1 cm = 5 units
