20, 17,16, 17, 18, 16, 18, 19<br><br>what is the mode of the data set?

pychu [463]

Answer:

16,17 and 18

Step-by-step explanation:

In statistics mode of a set of entries is the entry which is repeated maximum. There can be more than one mode in a set of entries. These are called mode,

Bimode ( two mode ) , trimode ( three mode ) and Multimode ( four or more ) .

Hence here our set of entries is,

20,17,16,17,18,16,18,19

arranging them in ascending order

16,16,17,17,18,18,19,20

hence in this case we see that 16,17and 18 all are getting repeated for two times, the maximum.

Hence we have a trimode here

16,17,18
