what is the formula of mean , median , mode ?
what is class, class size, class interval and class marks????? plz plz plz answer fast......or else i will fail.......plz
In a frequency distribution, the mid-value of a class is 20 and the width of the class is 8.then what is the lower limit ?
If mean of 5 observations x , x+2 , x+4 , x+6 , x+8 is 11.
Find the median of first three observations.
Plz help,
Find the missing frequencies f1 and f2 in the following frequeny distribution, if it is know that the mean of the distribution is 1.46

The mean of first 8 observations is 18 and last 8 observations is 20 . If the mean of all 15 observations is 19 , find the 8 th observation?
the two consecutive class marks of a distribution are 52 and 57. find the class limits of two intervals
whats the difference between class interval, class size,class limit,class mark and also ranges,width and length of rectangle ?
Find the value of p, if the mean of the following distribution is 20
x: 15 17 19 20+p 23
f: 2 3 4 5p 6
note : the method should be of sigma fixi.
Differentiate between class limits and true class limits.Give examples
what is the exact formula for ADJUSTED FREQUENCY??????????????
BECAUSE 2 VIDEOS OF THE SAME CHAPTER BUT OF OTHER LESSON SHOW DIFFERENT FORMULA SO WHICH ONE IS CORRECT.
