When the mean and median do not coincide, it typically indicates that the data distribution is skewed. In a positively skewed distribution, the mean is greater than the median, while in a negatively skewed distribution, the mean is less than the median. This discrepancy arises because the mean is sensitive to extreme values, whereas the median is resistant to outliers, making it a better measure of central tendency in skewed distributions. Understanding this difference helps in accurately interpreting the data's characteristics.

Will the mean and median in a symmetric distribution always be equal or approximately equal and Why?
In a symmetric distribution, the mean and median will always be equal. This is because symmetry implies that the distribution is balanced around a central point, which is where both the mean (the average) and the median (the middle value) will fall. Therefore, in perfectly symmetric distributions like the normal distribution, the mean, median, and mode coincide at the center. In practice, they may be approximately equal in symmetric distributions that are not perfectly symmetrical due to rounding or sampling variability.

Are the mean median and mode always numbers from a list of data?
the median and mode are but the mean is not
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 Percent of data is below the mean in a normal distribution?
In the normal distribution, the mean and median coincide, and 50% of the data are below the mean.

How do mean deviation from median?
The mean deviation from the median is equal to the mean minus the median.

Can ypu find the mean and median with data from a histogram?
You can estimate the median and the mean.
What is the definition of mean and median in math?
Mean is the average, and median is the middle number.
How does the mean compare to the median?
The mean and the median are both involved with a set of numbers. The mean refers to the average of the numbers. The median refers to the middle number of the numbers
How do you compare median to the mean in this set 10 8 8 8 4 6 9 3?
median = 8 mean = 7 mean < median.
