Question

can you tell me mean median and mode formula​

Answer 1

Answer:

Mode = L+h(fm−f1)(fm−f1)−(fm−f2) L + h ( f m − f 1 ) ( f m − f 1 ) − ( f m − f 2 )

meadian- The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.

mean-The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30.

Answer 2

Answer:

mean = {Sum of Observations} ÷ {Total number of Observations}.

mode=lowest score+highest score (fm-f1/(fm-f1)+(fm-f2))

median= lm+[(n/2-f)/fm]
