show the relative frequency distribution
The fx column in a Frequency Distribution Table is the frequency (f) multiplied by the Class Centre or score (x). If the score is 22. And the freqency for that score is 7. fx = 22*7 = 154 You can use the total of the fx column to find the mean. The total fx divided by the total frequency = Mean.

find the frequency before finding the percent total -_- :)
The answer depends on what information you do have.
A Gaussian distribution has the mean at the highest value. Sum all the values and divide by the number of values. * * * * * A very partial answer and one that does not address the question which was in the context of a frequency distribution table. If the frequencies are for grouped data, replace the range of each group by its midpoint. This, then, comprises the set of values, x, for the random variable. For each x there is an associated frequency, f. Multiply each x by its frequency and add these together. Divide the answer by the sum of the f values. That is the mean.
find the mean in a set of frequency distribution
You seem to be referring to the Pearson chi-square test-of-fit statistic. To do this you need not only the observed values in a frequency table (which you have) but the expected (or theoretical) values for that table.In practical situations the expected values are obtained by making some educated guess about what distribution the observed values came from, estimating the parameters of that distribution and then using the estimated distribution to obtain the required expected values to calculate the chi-square.In short, you need more information.
You find the total of all the frequencies, N. Then the percentage for any frequency is 100*frequency/N.
Range = Maximum value - Minimum value
it is used to find mean<median and mode of grouped data
Frequency is how often something occurs. Frequency distribution is how often something occurs within a group of separate categories or ranges. Say you had a list of exam scores from a class of students. You might want to find out how many people got between 0% and 10%, how many got between 11% and 20%, how many got between 21% and 30%, and so on. All you are interested in is the how many as compared to who actually got the scores. What you would be doing is creating a frequency distribution table. You would be finding out how many people got results in the various ranges, or how the frequency of results are distributed across these ranges.
The best time to use a frequency table is when you have disorganized raw data, that need to be sorted, usually to find trends in the data.
The length can be found by taking the larger number in the frequency group and subtracting it to find the range.
Platinum has a relative atomic weight of 195.09(you will not find 5.09 anywhere else on a periodic table.)
Frequency tables - particularly tidy ones - are usually rectangular in shape. So their angles are all 90 degrees.
To find the amount of moles in a compound, you divide the mass of the compound by the compound's relative atomic mass. (You can find this on a periodic table)
* To find the mean (or average) of a standard frequency table, you must firstly cross-multiply the frequncies with the independent variable in the left column. * Then, add up these products and divide by the total number of frequencies. * For grouped frequency tables, you must find a mid-point, a half-way value in each group, before cross-multiplying.
The main utility of a cumulative frequency curve is to show the distribution of the data points and its skew. It can be used to find the median, the upper and lower quartiles, and the range of the data.
Mendeleev arranged the elements in a table ordered by atomic mass, corresponding to relative molar mass as defined today.
You can find out what groups certain elements are in, and find there relative atomic masses. You can also find outy how reacticve they aRE AND HOW MANY ELECTRONS NEUTRONS AND PROTONS ARE IN CERTAIN ELEMENTS
The answer will depend on what you mean by "solve". Find the mean, median, mode, variance, standard error, standard deviation, quartiles, deciles, percentiles, cumulative distribution, goodness of fit to some distribution etc. The question needs to be a bit more specific than "solve".
if data is in the form of frequency distribution then the modal range is the interval containing the highest frequency of observations
Find a family friend or relative to let you do small work and pay you "under the table".
how do i find the median of a continuous probability distribution
An 11 year old cannot unless they find a relative who is capable of paying you "under the table"
