No, not always. Sometimes they are equal. Sometimes they are close to each other, but not exactly the same. Sometimes they are very different. It depends on the numbers that are being used to calculate the mean and median. The way each is calculated is different. The mean is got by adding all the numbers and dividing by the amount of numbers. The median is got by arranging the numbers in order and finding the middle value in the list, if there is an odd amount of numbers, or the value half way between the two middle values when there are an even amount of numbers.

How do mean deviation from median?
The mean deviation from the median is equal to the mean minus the median.
Are the mean and median equal in a normal distribution?
Yes.
Are the median and the mean always the same value?
No, not necessarily. They each measure central tendency but in different ways. The mean measures the average of all of the scores while the mean is the middle score. In a normal distribution the median and mean must be equal. In other data sets, they may or may not be equal. For example, the set {0, 1, 2, 3, 5, 7, 10} has a mean of 28/7 = 4 and a median of 3.
In a unimodal symmetrical distribution the mean is equal to?
The median and mode.
What are the characteristics of mean as a measure of central tendency?
One of the characteristics of mean when measuring central tendency is that when there are positively skewed distributions, the mean is always greater than the median. Another characteristic is that when there are negatively skewed distributions, the mean is always less than the median.
For a given data set the mean and median are always nearly equal?
No.
Are the mean and the median always equal?
No. They are equal only if the distribution is symmetrical.
How do mean deviation from median?
The mean deviation from the median is equal to the mean minus the median.
Are the mean median and mode always numbers from a list of data?
the median and mode are but the mean is not
How are the mode and median the same?
Mean, median, and mode are all equal in a normal distribution.
What is the median for 11 and 5?
Both the median and mean of these two numbers are equal to 8.
Are the mean and median equal in a normal distribution?
Yes.
Can the mean be equal to the median?
Yes, and they WILL be if the distribution is symmetrical.
Are the mean and median equal in a chi-square distribution?
No.
Are median and mean always similar?
No, not always. Median is the number that's in the middle of a group of numerical data. Mean is just the average of a set of numbers, which isn't always in the middle.
Are the median and the mean always the same value?
No, not necessarily. They each measure central tendency but in different ways. The mean measures the average of all of the scores while the mean is the middle score.

In a unimodal symmetrical distribution the mean is equal to?
The median and mode.
