finding grouped mean: you normally have a table like this : VISITS FREQ SUM <--to work out this, you times visits by freq. 0 5 0 <-- 1 13 13 <-- 2 21 42 <-- 3 7 21 <-- 4 4 16 <-- 50 92then work out the totals by adding them up (as shown) working out mean you have to do sum total / freq total mean= 92/50 hope this helped Claire, 15

Formula of mean for grouped data?
Mean = a + [
Can a grouped of data be grouped?
Not sure what a "grouped of data" means!
How do you find the first quartile in grouped data?
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.
What are the categories by which data are grouped?
Data can be grouped or ungrouped. The categories data are grouped in depend on the data. For example, data collected about people could be grouped as male/female, by ages, or some other common characteristic. Data collected about dogs could be grouped by breed of dog, age, long hair/short hair, or size.
How can you find the assumed mean of grouped data?
find assumed mean data is 46,55,52,59,63,47,56,50,51,55 ,
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

What is definition of grouped data?
Grouped means the grouping of relevant data after analysis. When raw data is analyzed in proper and meaningful way then its transformed into groups and these groups are known as grouped data.
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.
Definition of ungrouped data?
Ungrouped data is data that is not grouped in a specific order. Grouped data is a set of data that has unique characteristics in common.
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.
