हिन्दीIn step-deviation method, the mean \( \bar{x} \) is given by \( a + (\frac{\sum f_i u_i}{\sum f_i}) \times h \). What does \( h \) represent in this formula?
View Answer & Solution
Correct answer · Option B
Class size / width of class intervals
Explanation
In the step-deviation method, \( h \) is the uniform class size used to scale deviations \( u_i = \frac{x_i - a}{h} \).
