Which of the following is least affected if an extreme high outlier is added to your data mean median or standard deviation or ALL?
The median is least affected by an extreme outlier. Mean and standard deviation ARE affected by extreme outliers.
How do you calculate standard deviation using median?
You cannot because the standard deviation is not related to the median.
If mean is 8 median is 6 and standard deviation is 2 what is skewness?
Karl Pearson simplified the topic of skewness and gave us some formulas to help. The first is the Pearson mode or first skewness coefficient. It is defined by the (mean-median)/standard deviation. So in this case the Pearson mode is: (8-6)/2 =1 There is also the Pearson Median. This is also called second skewness coefficient. It is defined as 3(mean-median)/standard deviation which in this case is 6/2 =3 hence the distribution is positive skewed
Is the median closely related to variance and standard deviation?
No, it is not
What percentage of a normal distribution is within 2 standard deviations of the mean?
I believe the standard deviations are measured from the median, not the mean.1 Standard Deviation is 34% each side of median, so that is 68% total.2 Standard Deviations is 48% each side of median, so that is 96% total.
How do you calculate mean and Median smaller then Standard deviation?
In the same way that you calculate mean and median that are greater than the standard deviation!
Characteristics of mean median mode range variance standard deviation mean absolute deviation?
characteristics of mean
What is median of 25 through 39?
mean | 32 median | 32 standard deviation | 4.472 ========================================================================
What are the median and mode of a normal distribution if the mean is 22 and the standard deviation is 4?
The mean, median, and mode of a normal distribution are equal; in this case, 22. The standard deviation has no bearing on this question.
Which has the least variability Mean Standard Deviation 0.560 Median Standard Deviation 0.796?
msd 0.560
What is the mean absolute deviation of this set of numbers 3 9 27 81?
mean | 30 median | 18 standard deviation | 35.496
Which of the following is least affected if an extreme high outlier is added to your data mean median or standard deviation or ALL?
The median is least affected by an extreme outlier. Mean and standard deviation ARE affected by extreme outliers.
How do you calculate standard deviation using median?
You cannot because the standard deviation is not related to the median.
When the size of a representative sample increases does the mean range median or standard deviation decrease?
mean
What is the mean mode median standard deviation and standard error of 10 24 35 44 10 and 35?
Mean: 26.33 Median: 29.5 Mode: 10, 35 Standard Deviation: 14.1515 Standard Error: 5.7773
How do you find graph median by using standard deviation?
You cannot because the median of a distribution is not related to its standard deviation.
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.
