Answer:
Median and IQR
Step-by-step explanation:
Out of 3 central tendencies, mean, median and mode, median is the better measure.
This is due to
i) Mean is affected by extreme values
ii) Mean is not correct if more outliers are present
iii) Mean may not represent the nature of the data whether skewed right or left.
But median the middle entry is not affected by extreme items or outliers so median is better than mean,
For measure of spread, IQR is better since extreme items will show higher std deviation, and also some outliers mislead. But IQR gives a good idea.
