Calculate median and mode for following data :

23, 45, 46, 12, 34, 87, 78, 12, 65, 33, 19, 34, 55, 67, 81, 12, 56, 98, 11, 49, 50

Expert Answer:

The numbers in ascending order are:

11, 12, 12, 12, 19, 23, 33, 34, 34, 45, 46, 49, 50, 55, 56, 65, 67, 78, 81, 87, 98

As the number of observations (21) are odd,

Median = middle observation = 11th observation = 46


Mode is the observation that appears most often.
Here, 12 appears maximum number of times (thrice). So, 12 is the mode.
