Is Mean is more sensitive to skewness than the median?
If the distribution is positively skewed , then the mean will always be the highest estimate of central tendency and the mode will always be the lowest estimate of central tendency (If it is a uni-modal distribution). If the distribution is negatively skewed then mean will always be the lowest estimate of central tendency and the mode will be the highest estimate of central tendency. In both positive and negative skewed distribution the median will always be between the mean and the mode. If a distribution is less symmetrical and more skewed, you are better of using the median over the mean.
If the mean of a symmetric distribution is 130 which of these values could be the median of the distribution?
If it is a symmetric distribution, the median must be 130.
When the mean of a distribution of scores of measures is higher than the median the distribution would be?
The distribution is skewed to the right.
What is the median to the following distribution 25 33 43 43?
It is 38.
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.
Does mode equal median in a normal distribution?
Yes, mode equals median in a normal distribution.
Does mode equals the median normal distribution?
Yes it is. The normal distribution is symmetrical around the mode. Therefore the median has to be the same :)
In a normal distribution you will always know that?
The mean is the same as the mode and median.
Do the mean median and mode of a collection of numbers always have to be different?
No, in a normal distribution they are the same.
What is the distribution when the mean median and mode are the same?
The normal distribution.
What is the median of a normal distribution to outlier as lunar perigee is to lunar?
The median of a normal distribution to outlier as lunar perigee is to lunar is an elliptical orbit.
The mean of a symmetrical distribution is 40What is its median?
for symmetrical distributions your mean equals the median. that is one of the properties of the symmetrical distribution.
How does the median affect the graph of a normal distribution?
A normal distribution is symmetrical; the mean, median and mode are all the same, on the line of symmetry (middle) of the graph.
Are the mean and median equal in a normal distribution?
Yes.
Is the mode and median equal in a normal distribution?
Yes.
How to find the median of a log normal distribution?
The formula is: median of lognormal = exp(u)
How are the mode and median the same?
Mean, median, and mode are all equal in a normal distribution.
