The table below show the Marks of score out of 10 by some candidate in a test Marks=1 2 3 4 5 6 7 8
number of candidate=2 3 5 7 8 13 7 5
1 From the table find modal Mark
2 how many candidate took the test
3 the mean Marks​

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

but less than;

an angle that measures
