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
How is a frequency distribution used?
it is used to find mean<median and mode of grouped data
Which measures of central location always have only one value for a set of grouped or ungrouped data?
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
Can you find the mean of qualitative data?
no
How do you find the mean in a set of data?

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.

Formula of mean for grouped data?
Mean = a + [
How can you find mean median and mode for GROUPED data?
Mean, median and mode are ways to find averages. The mode is the most common answer in a set of data. The median the number that is in the middle when the numbers are put in order. The mean is the statical average.
How do you find the harmonic and geometric mean for grouped data?
The geometric-harmonic mean of grouped data can be formed as a sequence defined as g(n+1) = square root(g(n)*h(n)) and h(n+1) = (2/((1/g(n)) + (1/h(n)))). Essentially, this means both sequences will converge to the mean, which is the geometric harmonic mean.
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
Which measures of central location always have only one value for a set of grouped or ungrouped data?
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
How do you find assumed mean?
hey u can choose any number from the frequency to find the assumed mean suppose u have 8 frequencies u can assume 4 as the mean
What does filed mean?
Computer File is the data grouped into one unit under one name using the particular software. Data is the digitalized information.
