Question

please help me anyone give me right answer with draw diagram help me..​

Answer 1

Step-by-step explanation:

Mean = sigma xifi / sigma fi

Median = l + n/2 - CF /F × h

Mode = l + (f 1- f 0) / ( 2f1 - f0 - f2 ) ×h

Answer 2

Answer:

Mean -

$\frac{ sum \: of \: all \: the \: observation}{number \: of \: observations}$

Mode -

L + (fm - f1) x h / (fm - f1) + (fm - f2)

L - Lower limit of mode of class

h - Size of class modal

fm - Frequency of the class

f1 - Frequency of first mode of class

f2 - Frequency of first mode of class

Median -

For odd no. of observation:-

Arrange the observation in ascending or descending order and the middle no. is the median of the observation .

For even no. of observation:-

Arrange the observation in ascending or descending order and after getting the middle two nos. then,

$\frac{sum \: of \: middle \: two \: nos.}{2}$

Thank you very much for the thanks
