Which measure of variation is appropriate when using the mean and which is appropriate when using the median?
When using the mean: the variance or standard deviation. When using the median: the range or inter-quartile range.
What is the definition of mean and median in math?
Mean is the average, and median is the middle number.
What are the advantages and disadvantages of median?
Median cannot be used for qualitative data (a mode can).The sampling distribution of the median is complicated (the mean is well studied).Median can usually be used for data that can be ordered without there being a ratio scale. For example, "small-medium-large", or "very negative-negative-neutral-positive-very positive". A mean cannot be calculated without arbitrarily assigning a numerical value to the terms.A median is not dependent on all the values which means that it is not distorted by outliers (extreme values).It is easy to find the median value from cumulative frequency charts.
When is the median more useful than the mean?
When the distribution has outliers. They will skew the mean but will not affect the median.
How come the mean is less than the median?
If the distribution is not symmetric, the mean will be different from the median. A negatively skewed distribution will have a mean hat is smaller than the median, provided it is unimodal.
What are three ways of calculating an '' average ''?
Mean Median And Mode
Why calculate for the mean and median in relation to a sample?
Both the mean and median represent the center of a distribution. Calculating the mean is easier, but may be more affected by outliers or extreme values. The median is more robust.
What are the advantages of using median?
When someone asks a for an "average" value, that can mean a couple of different things. "Mean," "median," and "mode" are all values that are used to relate what the "center" or "average" of a distribution of values is. Each one has their advantages and disadvantages. The median is the value that divides the distribution exactly into halves - 50% is below it, and 50% above it. The median may not actually occur in the distribution, but it is the "balance point" of the distribution. The main advantage of the median is that it is not affected by outliers as the mean is and the mode can be. In distributions with a clear skew, such as housing prices or wages, using the median provides a much better estimate of what the "average" is.

Is the median affected by the mean?
The median is the value which seperates the upper and lower half of a set of numbers. The mean is the average value between two or more numbers. In calculating a set of numbers, specifically a set of averages, the median may indeed be effected by the mean.
Can you think of a situation where you'd use the mode over the median or mean?
You could use mode over median or mean when calculating probability. Mode calculates the greatest number of times an object or number will appear.
What are the advantages and disadvantages of a dot plot?
It does not display a directly display a median, mean, or range.
How do you use mean median mode and range in real life?
Cashiers don't use median and mode. Not typically. I've never really been in a situation in real life in which i have used any of those methods of calculating averages. Median and mode are useful when studying statistics or calculating demographics, but most people don't have to do that outside of marketing or record keeping.

Advantages and disadvantages of median in statistics?
MEDIANUse the median to describe the middle of a set of data that does have an outlier.Advantages:• Extreme values (outliers) do not affect the median as strongly as they do the mean.• Useful when comparing sets of data.• It is unique - there is only one answer.Disadvantages:• Not as popular as mean.
Why is calculating the mean average better than the median or mode?
well when answering the mean you take the average of all the numbers so it be approxiamently around the answers and each number can affect the mean in many ways while a median is when you put the numbers in order and you get the middle number, because it is a middle the number can be far away from the beginning number or ending number. Mode is when the numbers appear the most and when picking mode it can be a dramatic change from the numbers around it. That is why calculating the mean average is better than take the median and mode, but sometimes some problems work better dealing with mode or median.
Do you take the outlier out when calculating mean and median?
No. The mean is calculated by adding all of the numbers, then dividing that sum by [how many numbers]. The trimmed meandoes remove some outliers (same number of outliers at top and bottom, though). The median is the middle number of a sorted set.
