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 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 does the word indicate mean in math?
A mathematical mean is the average of a group of numbers. To find it, you add all of the numbers you're being asked to find the mean for and then divide by the number of numbers you added. In other words, the average.* * * * *There are other means which are useful in other circumstances. The two common ones are the geometric mean and the harmonic mean.The geometric mean, for a group of n positive numbers is the nth root of the product of the numbers.So, G(4,6,9) = cuberoot(4*6*9) =cuberoot(216) = 6The geometric mean is useful with numbers that are used as multipliers, such as growth rates.The harmonic mean of n numbers x1, x2, x3 ,... xn is the number H such thatn/H = 1/x1 + 1/x2 + 1/x3 + ... + 1/xnThe harmonic mean is useful when the average of rates is desired. For example, if you travel k miles at x mph and another k miles at y mph, your average speed would be H(x,y).Mean is another name for 'average'. Here you add up the scores and divide this new number by how many scores there are.in notation this is (Sigma (xf-xi)) / x

Median formula for grouped data?
Simple answer:Divide the total number of observations (plus 1, if small) by 2 to find the middle rank.Look at the cumulative frequencies for the grouped data and find the group in which the middle rank would appear. That is the median group.More sophisticated answer:Withing the median group, interpolate.
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.
