NCERT Solutions for Class 7 Maths Chapter 3 Data Handling Exercise 3.2<\/h2>\n

Question 1.
\nThe scores in mathematics test (out of 25) of 15 students are as follows:
\n19, 25, 23, 20, 9, 20,15, 10, 5, 16, 25, 20, 24, 12, 20
\nFind the mode and median of this data. Are they same?
\nAnswer:
\nArrange the given data in ascending order, we get, 5, 9, 10,12, 15,16, 19, 20, 20, 20, 20, 23, 24, 25, 25
\n(a) Mode of the data = 20
\n20 is repeated 4 times<\/p>\n

(b) Median of the data = 20
\nSince the middle value of the data is 20
\nObviously, here the mode and median are the same.<\/p>\n

\"NCERT<\/p>\n

Question 2.
\nThe runs scored in a cricket match by 11 players are as follows:
\n6,15,120, 50, 100, 80, 10,15, 8,10, 15
\nFind the mean, mode and median of this data. Are the three same?
\nAnswer:
\nArrange the given data in ascending order, we get, 6, 8, 10, 10, 15, 15, 15, 50, 80, 100, 120
\n(i) Mean of the data
\n\"NCERT<\/p>\n

(ii) Since 15 is repeated 3 times, the mode of the data = 15
\n(iii) The value of the middle observation is 15. The Median of the data =15.
\nHere mean, median and mode are not the same.<\/p>\n

Question 3.
\nThe weights (in kg) of 15 students of a class are:
\n38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 38,43, 38, 47
\n(i) Find the mode and median of this data.
\n(ii) Is there more than one mode?
\nAnswer:
\nArrange the given data in ascending order, we get,
\n32, 35, 36, 37, 38, 38, 38, 40, 42, 43, 43, 43, 45, 47, 50
\n(i) Since 38 and 43 are repeated 3 times, the mode of the data = 38 and 43
\nThe value of the middle observation is 40.
\n\u2234 Median of the data = 40<\/p>\n

(ii) Yes, there are more than one mode.<\/p>\n

\"NCERT<\/p>\n

Question 4.
\nFind the mode and median of the data: 13,16, 12,14, 19,12,14, 13,14
\nAnswer:
\nArrange the given data in ascending order, we get, 12, 12, 13, 13, 14, 14, 14, 16, 19
\nSince 14 is repeated 3 times, the mode of the data = 14
\nAgain the value of the middle observation is 14, median of the data = 14<\/p>\n

Question 5.
\nTell whether the following statements is true or false:
\n(i) The mode is always one of the numbers in a data.
\n(ii) The mean is one of the numbers in a data.
\n(iii) The median is always one of the numbers in a data.
\n(iv) The data 6, 4, 3, 8, 9, 12, 13, 9 has mean 9.
\nAnswer:
\n(i) True
\n(ii) False
\n(iii) True
\n(iv) False<\/p>\n","protected":false},"excerpt":{"rendered":"
