If x1, x2,… xn, are observations with respective frequencies f1, f2,, . . ., fn then this means observation x1, occurs f1 times, x2, occurs f2, times, and so on. Arithmetic Mean of grouped data using step deviation - formula. ... A= The middle value that is assumed as the mean for calculation, ∑i=1nfi= Sum of the frequencies given, can be denoted by N. Ui is a new variable obtained from variable Xi by subtracting the assumed mean M and dividing the result by (normally) the class width H. e.g. Ui = (Xi - M)/H. The purpose of this exercise is to obtain values for Ui which are easier to handle. #Step_deviation_method_to_find_mean #class10_board_important_questions #statistics Like, subscribe and share😇 Smart way of learning.................
