Anyone who has a basic statistical background knows how to calculate the (arithmetic) mean - just sum up the individual values and divide the result by the number of values. These statistical programs can be expensive for an individual to obtain. Multivariate techniques are complex and involve high level mathematics that require a statistical program to analyze the data. It may also be called a center or location of the distribution. The median is sometimes referred to as a measure of location as it tells us where the data are. As we can see mean and median does not vary drastically, but mode on the other hand varies. Each does this in a slightly different way and may give a different answer if the data set is a skewed (asymmetrical) distribution (see diagram below). With the exception of cases where there are obvious extreme values, the mean is the value usually used to indicate the centre of a. a person’s height and you switch from meter to centimeter. Arithmetic mean is not an ideal average for distributions with extreme items or open-end classes. In general, means take outliers into account, medians don’t. Speech came before writing.

I feel median imputation will work better because it is a number that is already present in the data set and is less susceptible to outlier errors as compared to mean imputation. So is the median, and so is the mode except when there are more than one value with the highest frequency density. It can be better understood with the help of an example monthly income of 5 individuals is $2000, $4000, $6000, $8000 and $10000 than the middle figure which is $6000 is the median of the above data.
