Class 10 Mathematics Worksheet for Chapter 14 Statistics

 

Statistics

Q.- The class marks of a distribution are 82, 88,94, 100, 106, 112 and 118. Determine the class size and the classes.

Sol. The class size is the difference between two consecutive class marks. ∴Class size = 88 – 82 = 6. Now 82 is the class mark of the first class whose width is 6.  ∴ Class limits of the first class are 82 – 6/2 and 82 + 6/2

i.e. 79 and 85. Thus, the first class is 79-85.
Similarly, the other classes are 85–91, 91– 97, 97–103, 103 –109, 109 –115 and 115 –121.
 
Ex.14 The class marks of a distribution are 13, 17,21, 25 and 29. Find the true class limits.
 
Sol. The class marks are 13, 17, 21, 25 and 29.
The class marks are uniformly spaced.
Class size = difference between two consecutive
class marks
= 17 – 13 = 4
Half of the class size = 4/2 = 2
To find the classes one has to subtract 2 from and add 2 to each of the class marks.
Hence, the classes are
11– 15
15 – 19
19 – 23
23 – 27
27 – 31
 
Since the classes are exclusive, the true class limits are the same as the class limits. So the lower class limits as well as the true lower class limits are 11, 15, 19, 23 and 27. The upper class limits as well as the true upper class limits are 15, 19, 23, 27 and 31.
 
Q.- Convert the given simple frequency series into a:
(i) Less than cumulative frequency series.
(ii) More than cumulative frequency series.

Q.- Convert the following more than cumulative frequency series into simple frequency series.

statistics notes 16

Q.- Drawn ogive for the following frequency distribution by less than method

statistics notes 17

Sol. We first prepare the cumulative frequency distribution table by less than method as
given below :
statistics notes 18
Other thanthe given class intervals, we assume a class – 10-0 before the first class interval 0-10 with zero frequency.
Now, we mark the upper class limits
(including the imagined class) along X-axis on a suitable scale and the cumulative frequencies along Y-axis on a suitable scale.
Thus, we plot the points
(0, 0), (10, 7), (20, 17), (30, 40), (40, 91), (50,97), and (60, 100)

statistics notes 19

Now, we join the plotted points by a free
hand curve to obtain the required ogive.
 
Q.- Draw a cumulative frequency curve for the following frequency distribution by less than method

statistics notes 20

Sol. The given frequency distribution is not continuous. So, we first make it continuous and prepare the cumulative frequency distribution as under :

statistics notes 21

Now, we plot points (9.5, 5), (19.5, 20), (29.5,40), (39.5, 63), (49.5, 80), (59.5, 91) and (69.5, 100) and join them by a free hand smooth curve to obtain the required ogive as
shown in Fig.

statistics notes 22

Q.- The temperature of a patient, admitted in a hospital with typhoid fever, taken at different times of the day are given below. Draw the temperature-time graph to reprents the data:

statistics notes 23

Sol. In order to draw the temperature-time graph, we represent time (in hours) on the x-axis and the temperature in ºF on the y-axis. We first plot the ordered pairs (6, 102), (8, 100), (10, 99), (12, 103), (14, 100), (16, 102) and (18, 99) as points and then join them by line segments as shown in Fig.
