Mean filtering is linear but median filtering is non-linear.
What is the difference between mean and median salary?
the mean is the average of all the salaries an the the median is the number that falls in the middle
How is the choice made between mean and median to describe the typical value related to the shape of the data distribution?
Either can be used for symmetrical distributions. For skewed data, the median may be more a appropriate measure of the central tendency - the "average".
What is the formula for the stastictics?
The formula for statistics can vary depending on the specific statistic being calculated. Common formulas include mean (average), median (middle value), mode (most frequent value), standard deviation (measure of dispersion), and correlation coefficient (relationship between variables). It is important to determine the appropriate formula based on the data and the statistical analysis being conducted.
What is the median between 21 and 24?

What is the median between 25 and 50?
The median of 25 and 50 is also their arithmetic mean. 37.5
What is the relation between mean median and mode?
In a symmetric distribution, the mean and the median are the same. Otherwise there is no relation. In symmetric distributions with only one mode, the mode will coincide with the mean and median, but otherwise there is no relation.
What is the relationship between mean and median?
Mean is the average, median is the middle. The get the mean just add up all the numbers and divide by how many numbers you added. The get median just find the middle number
