Question

what are discrete series in QT?​

Answer 1

Answer:

Discrete series means where frequencies of a variable are given but the variable is without class intervals. Here the mean can be found by Three Methods. ... Here each frequency is multiplied by the variable, taking the total and dividing total by total number of frequencies, we get X

Explanation:

For example : the class 20–30 contains 6 obervations : 25, 25, 20, 22, 25 and 28. So when these data are grouped as a class 20–30 in the frequency distribution,the latter provides only the number of records in that class (i.e. frequency = 6) but not there actual values.

Answer 2

Answer:

In discrete series, there are frequencies corresponding to different values of the variables. Values of the variables are arranged in groups which are exactly measurable.
