Question

What is the formulae to find step deviation in mean explain the term

Answer 1

Answer:

Step-by-step explanation:

Mean = assume mean(xi)+ (sumission of fiui/simission of fi)×class height.

Answer 2

Answer:

$step \: deviation \: method \\ = a+( sigma fi \times ui/ sigmafi) × h \\ </p><p></p><p>a= assumed \: mean \\ </p><p>sigma \: fi \times \: ui= sum \: of fi \times ui \\ </p><p>sigma fi= sum \: of \: frequency</p><p>h= class size \:$
