Information collected in the form of facts, numerical figures, tables etc., is called

Data collected from a source like registers is called

Range of the data “18, 24, 15, 17, 33, 16, 29, 45, 12, 3, 33, 21” is

0 – 10, 11 – 20, 21 – 30, 31 – 40. The real lower limit of the class 21 – 30 is

For a data, the range is

The temperatures of a city recorded during a week are 42°, 35°, 44°, 33°, 39°, 45° and 42°. The average temperature is

In a deviation problem $\sum f_i{d}_i\backslash sum\; f\_id\_i$  = – 12 and A = 15; $\sum f\backslash sum\; f$ = 20 then $\bar{x}\backslash bar\; x$ =

Median of 3, 7, 4, 6 and 12 is

Median of the data 5,8, 9, x, 11, 13 is 9.5 (given that data is arraned in ascending order) then x is

Formula to find mean for a grouped data is
