What are the similarities and differences between these data sets in terms of their centers and their variability?

data set a: 16, 10, 18, 24

data set b: 21, 14, 16, 14, 19

select from the drop-down menus to correctly complete the statements.
comparing the centers of the data sets, the median for data set a is the median for data set b.

further, based on the range, data set is more variable.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
