no. it is the middle number. if u have the numbers 3, 12, and 5, u will have to put them in order from least to greatest. then u find the middle number which is 5. if u have more numbers like 23, 7, 34, 75, and 46, u would do this work:
order from least to greatest: 7, 23, 34, 46, 75
find the middle number: 5 numbers in total; 7, 23, 34,46, 75.

Why are the measures of dispersion necessary to describe a set of data?
Sets of data have many characteristics. The central location (mean, median) is one measure. But you can have different data sets with the same mean. So a measure of dispersion is used to determine whether there is a little or a lot of variability within the set. Sometimes it is necessary to look at higher order measures like the skewness, kurtosis.
What is the median is a measure of?
the median is the middle like 2,3,5,7,4,2.8. the median is 7 because it is in the middle.
Why standard deviation is best measure of dispersion?
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
Why is the median a more stable measure of central tendency than the mean?
in general,mean is more stable than median but in the case of extreme values it is better to consider median a stable measure than mean.
What is the appropriate measure of central tendency for an ordinal scale?
median
