The first five whole numbers are     We know, Arithmetic mean   Therefore, mean of the first five whole numbers is 
Numbers Frequency 1 1 2 2 3 1 4 3 5 5 6 4 7 2 8 1 9 1 (i)  is the highest number. (ii)  is the lowest number (iii) Range of the data = Highest number - Lowest number (iv) Arithmetic mean =  Therefore, mean of the data is     
Data Tally bars Number of times 12     3 13     4 14   5 15    10 16    6 18     1 19       1 Clearly, 15 occurs 10 times. Therefore, 15 is the mode of the data.  
(i) Given, 2, 6, 5, 3, 0, 3, 4, 3, 2, 4, 5, 2, 4 Arranging in ascending order: Here, 2, 3 and 4 all occur three times. Therefore, all three are modes of the data.   (ii) Arranging in ascending order: Here,  occurs 6 times. Therefore,  is the mode of the data.
Given number are :   and  Their average =  Average between  =   Average between  =    Average between  =   Average between   =  Therefore, 5 numbers between   and  are:
