What is a situation in which the median of a data set would be more useful than the mean?
The median is more useful than the mean in situations where the data set contains outliers or is skewed. For example, in household income data, where a few extremely high incomes can distort the average, the median provides a better representation of the typical income level. This makes the median a more reliable measure for understanding central tendency in such cases.
What is the Median of 8 5 9 2 2?
The median is 5, because two values (2 and 2) are less than 5, and an equal number of values (8 and 9) are greater than 5. Generally speaking, the median is more informative than the average (mean), although a proper calculation of a "typical value" of a list of values depends on what the typical value will be used for.
What do these data sets illustrate about the resistance of the median and mean?
Data sets illustrate that the median is more resistant to outliers and extreme values than the mean. While the mean can be significantly affected by extreme data points, causing it to misrepresent the central tendency, the median remains stable as it focuses solely on the middle value of a sorted data set. This property makes the median a better measure of central tendency in skewed distributions. Thus, when analyzing data, choosing the median over the mean can provide a clearer picture of the typical value.
How do the mean and median compareas measures of center?
The mean is the arithmetic average of a set of values, while the median is the middle value when the data is ordered. In symmetrical distributions, the mean and median are typically close or equal, but in skewed distributions, the mean can be influenced by extreme values, making it higher or lower than the median. Thus, the median is often preferred as a measure of center for skewed data, as it provides a better representation of the typical value without being affected by outliers.
What is median if even?
In maths, the median is connected with the mode, mean. Help learn theese by singing a song, more of a chant though. Mode most Median middle Mean add up and divide Mode most Median middle Mean add up and divide!!
Does typical mean average or median?
Average. this is because the typical is what the total divided by the number of items. this is also what the mean (or average) is.
Does mode median or mean accurately reflect typical?
In the appropriate context, they do.

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 is the choice made between mean and median to describe the typical value related to the shape of the data distribution?
Either can be used for symmetrical distributions. For skewed data, the median may be more a appropriate measure of the central tendency - the "average".
Would you use the mean median or mode to most accurately reflect the typical number of pages read by a student?
Mean.
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 is the Median of 8 5 9 2 2?

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.

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