STATISTICS

MEASURES OF CENTRAL TENDENCY
Mean,median and mode
mean
           the mean of a set of data is the sum of the data divided by the number of items the data set.
example:find mean 1,1,5,2,2,4,2,5
solution
mean= 1+1+5+2+2+4+2+5
                        8
ans:2.75
Median
        is the middle number of the ordered data or the mean of the midde two numbers.
                   mathematically
example find the median given that 7,11,15,17,20,20
solution
median=15+17
                2
ans:16
note
when there is an odd number of data the median is the middle number of ordered set.When there is an even number of data the median is the mean of the two middle numbers
mode
       is the number or numbers that occurs most often.
example. 50,45,45,52,49,45,56
mode is 45
quiz
find the median,mean and mode for each set of data.round to the nearest thenth if necessary;
(1)14,5,16,7,15,9,2,14,6
(2)29,14,80,59,78,30,59,69,55,50.
