Given the following formula for Median i.e
L+ (N/2 – C) X (L2 – L1) , here ‘C’ represents-
f
The frequency of median class
Frequency of post median class
Cumulative frequency of pre-median class
Cumulative frequency of median class
The first step of statistical investigation starts with

Median
Mode
The positional average of central tendency is called as—
Mode
Mean
Median
Geometric mean
The relationship between Mean, Median & Mode is as under
Mode = 4 Median – 3 Mean
Mode = 3 Median – 2 Mean
Mode = 2 Median – 3 Mean
Mode = 3 Mean – 2 Median

Median
Geometric mean
Harmonic mean
Mode

(a)
1. Quantitative and--------------- are the two major categories of statistical data.
(a)
1. The measurement of weight, age comes under the category of -------------- scale.
(a)
The property of concentration of values around a central value is known as ---------------------- tendency.
(a)
1. Median of a set of value is the --------------------- value when the data is arranged is ascending or descending order of magnitude.
(a)
The property of deviation of values from the ----------------- is called dispersion.
(a)
The ------------------- of the sampling distribution of the statistics is known as Standard Error (S.E.).
(a)
Parametric and -------------------- are the two categories of testing of hypothesis
(a)
Median is also called --------------------------- average
(a)
Standard deviation is also known as ------------------
(a)
