the mode and mean is given by 7 and 8 respectively.then the median is;, 1/13, 13/3, 23/3, 33, the mean of the data 13,15,16,17,19,20 is;, 30/2, 31/2, 33/2, 35/2, if the mean of first n natural numbers is 3n/5,then the value of n is, 3, 4, 5, 6, the class interval of a given observation is 10 to 15,then the class mark for this interval will be;, 11.5, 12.5, 12, 14, if the sum of frequencies is 24,then the value of x in the observation; x,5,6,1,2 will be;, 4, 6, 8, 10, construction of a cumulative frequency table is useful in determining the, mean, median, mode, all the above three measures, the empiricial relationship between the three measures of central tendency is;, 3 median=mode+2 mean, 2 median=mode+ 2 mean, 3 median=mode + mean 2, 3 median = mode-2 mean, the method used to find the mean of given data is, direct method, assumed mean method, step deviation method, all the above, mode and mean of a data are 12k and 15a. median of the data is;, 12k, 14k, 15k, 16k, mode is the;, middle most frequent value, least frequent value, maximum frequent value, none of these
