Answer» (i) The size of each class into which a range of a variable is divided, as represented by the divisions of a histogram or bar chart. (ii) Individual Series is a statistical series in which the all the observations are listed out and all the observations have a frequency of 1. (iii) A Frequency array is an array of frequencies according to variate values, that is to say, a frequency distribution. The term “array” is often used for the individual frequency distributions which form the separate rows and columns of a bivariate frequency table. (iv) A frequency distribution is an overview of all distinct values in some variable and the number of times they occur. That is, a frequency distribution tells how frequencies are distributed over values. Frequency distributions are mostly used for summarizing categorical variables. |
