The runs scored in a cricket match by 11 players is as follows:6, 15, 120, 50, 100, 80, 10, 15, 8, 10, 15Find the mean, mode and median of this data. Are the three same?3. The weights (in kg.) of 15 students of a class are:38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 38, 43, 38, 47(1) Find the mode and median of this data.(i) Is there more than one mode?4. Find the mode and median of the data: 13,16, 12, 14, 19, 12, 14, 13, 145. Tell whether the statement is true or false:1) The mode is always one of the numbers in a data.() The mean is one of the numbers in a data.The median is always one of the numbers in a data.(iv) The data 6, 4, 3, 8, 9, 12, 13,9 has mean 9.B |

Answer» Answer: Answer is (1). Given the scores in mathematics test (out of 25) of 15 students is as follows 19,25,23,20,9,20,15,10,5,16,25,20,24,12,20 Mode means which observation is most frequently occurred Here OBSERVE that 20 is most frequently occurred so mode is 20. __(1) FIRST of all average the data in ascending order 5,9,10,12,15,16,19,20,20,20,20,23,24,25,25 Here observe that no of observations (n)= 15 So median is 2 N+1 th term median = 2 15+1 th term = 8 th = 2 16 th median = 20 __(2) from (1) & (2) mode = median (Both are same) Answer (2). Ascending order the data is, 6,8,10,10,15,15,15,50,80,100,120 Sum of runs = 6+ 8+ 10+ 10+ 15+ 15+ 15+ 50+ 80+ 100+ 120= 429 Number of matches = 11 Mean= 11 429 =39 Median= Middle value of the data = 15 Mode=Most occuring observation of the data = 15 (3 times) Three are not same Answer (3). ARRANGING the given data in ascending order, 32,35,36,37,38,38,38,40,42,43,43,45,47,50 Mode = 38 As the frequency of 38 is most i.e. three Median = 38 Answer (4). ⇒ Mode is the frequently OCCURRING observation in a data. Now, we will arrange the data in ascending order we get, 12,12,13,13,14,14,14,16,19 So, we can SEE 14 number occurs 3 times. ∴ Mode is 14 ⇒ Median is the middle most observation. ∴ Median will be 5th number which is 14 . ∴ median is 14 Answer (5). i) True ii) False iii) True iv) False |
