To calculate the median, subtract the lesser number of the range from the greater number, and divide the result by two. Then add this result to the lesser number of the range. For example, the median of age range 15-19 is 17, and the median of age range 40-49 is 44.5.

What is the median average age?
Methodology. Median age is the age that divides a population into two numerically equally sized groups; that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population.
Is median age the same as average age?
Mean age is the average age of the people. Median age is the point where half the population is above and half are below it. The median gives a slightly better picture of what the age distribution looks like.
What is a good median age?
Moreover, median ages are typically 20 – 40, but people can live to 100 and more (an increasing and noticeable proportion of the population of modern countries now lives beyond 100). People of such age have 1.5 to 4 times the influence on the mean than they do on the median compared to very young people.

Why is median age?
Median age provides an important single indicator of the age distribution of a population. It provides the age ‘midpoint’ of a population; there are the same number of people who are older than the median age as there are younger than it.

What is a median example?
Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1 , 4, 7) , the number 4 is in the middle.
Why is median bad?
But this is bought at a cost: medians ignore all outliers because they ignore all value in your dataset, except the value of the single central item (or two items in the case of a tie). Relative position is all that counts. This means you’re throwing away data every time you use the median.

Is median A measure of center?
There are three measures of the “center” of the data.The median is the data value in the middle of a sorted list of data. To find it, you put the data in order, and then determine which data value is in the middle of the data set. The mean is the arithmetic average of the numbers.
For which distribution is the median the best measure of center?
skewed distribution
The median is usually preferred to other measures of central tendency when your data set is skewed (i.e., forms a skewed distribution) or you are dealing with ordinal data.
Which is better mean or median?
Unlike the mean, the median value doesn’t depend on all the values in the dataset. Consequently, when some of the values are more extreme, the effect on the median is smaller.When you have a skewed distribution, the median is a better measure of central tendency than the mean.
