They are 30 and 50 rounded to the nearest 10
32+28=50
21, 28, 35, 42, 49.
The variance is: 500.0
49/50=0.98 To get this answer divide 49 by 50.
No.
They are 30 and 50 rounded to the nearest 10
They are: 7 14 21 28 35 42 and 49
32+28=50
50
The variance is: 500.0
21, 28, 35, 42, 49.
50/50 the odds are split
49/50=0.98 To get this answer divide 49 by 50.
49/50:= 49 ÷ 50= 0.98 in decimal
Its easy 50=49+1 (7*7)=49 and (7/7)=1 50=(7*7)+(7/7)
First mean is calculated.Then calculate deviations from the mean.Then the deviations are squared.Then the squared deviations are summed up.Finally this sum is divided by number of items for which the variance is being calculated. For a population, it is by the number of values, in this case 12. If it is a sample, then we divide by one less, which is 11,For these figures, the variance for the population is 11069.24306. If it is a sample, it is 12075.53788 as the result.
