Yield of soyabean per acre in quintal in Mukund's field for 7 years was 10, 7, 5, 3, 9, 6, 9. Find the mean of yield per acre.
उत्तर
Mean = `"The sum of all observations in the data"/"Total number of observations"`
Mean = ` ( 10 + 7 + 5 + 3 + 9 + 6 + 9 ) / 7`
= `49 / 7`
= 7
So, the mean of yield per acre is 7.
