Arithmetic Mean (in Hindi)

Weighted mean is infact the mean of observations which are in descrete series ie mean for frequency distribution

Weighted Mean (in Hindi)

Combined mean - this is very simple topic  but  used in  standard deviation so we need to learn it

Combined Mean (in Hindi)

Geometric mean and Hormonic mean - aee also we study in sequence and series  . Same here also

Geometric Mean and Harmonic Mean (in Hindi)

Median - it depends on number of terms and writing the data in order

Median for Individual Series (in Hindi)

Relation between mean mode and median is 
Mode =3Median-2Mean

Relation Between Mean Mode Median (in Hindi)

Mean deviation is calculated generally about the mean and median which is given by sum of all deviation / total number of observations

Mean Deviation about Mean and Median (in Hindi)

Variance is a measure of despersion by taking mean of square of  deviation of each observatiin from mean

Variance (in Hindi)

Standard deviation is simply squareroot of variance so once you finished variance you just take its squareroot to get SD

Standard variation
