Calculating quartile deviation for grouped and ungrouped data?
(q3-q1)/2
What does one standard deviation mean?
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
Formula of mean for grouped data?
Mean = a + [
I am given 9 15 28 10 and 8 what is the mean absolute deviation for this data?
The mean deviation or absolute mean deviation is the sum of the differences between data values and the mean, divided by the count. In this case the MAD is 6.
Can a grouped of data be grouped?
Not sure what a "grouped of data" means!
How do you get the Quartile Deviation in a grouped data?
Test
What is a coded-deviation method in statistics?
Differing from standard deviations, the coded deviation method finds the mean of grouped data from the assumed mean using unit deviations. This is a shorter way to find the mean.
How do you identify group data or ungroup data in standard deviation?
You cannot. If you are told the standard deviation of a variable there is no way to tell whether that was derived from grouped or ungrouped data.

What does one standard deviation mean?
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
How do you find number of observations in a given statistical grouped data within 1.6 standard deviation?
1.6*s+mean and1.6*s and count numbers between them
Is the mean of the grouped data is equal to the mean of ungrouped data?
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
Relation between mean and standard deviation?
Standard deviation is the variance from the mean of the data.
Formula of mean for grouped data?
Mean = a + [
Difference between standard deviation and mean devition?
The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. The standard deviation sigma of a probability distribution is defined as the square root of the variance sigma^2,
What is the standard deviation?
The standard deviation of a set of data is a measure of the spread of the observations. It is the square root of the mean squared deviations from the mean of the data.
I am given 9 15 28 10 and 8 what is the mean absolute deviation for this data?
The mean deviation or absolute mean deviation is the sum of the differences between data values and the mean, divided by the count. In this case the MAD is 6.
