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.
The square of the hypotenuse minus the square of the leg you know will give you the square of the unknown leg.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
336 cubic inches.
In a square, all four sides are of equal length. Divide the perimeter by four to find the length of each side: 12 ÷ 4 = 3 ft
ask your math tutor if you have left school and dont know this then ask your son if you dont have a son then ask your dog if you dont have a dog ask clint eastwood
find the frequency before finding the percent total -_- :)
How do you find missed frequency if median and mode are given
A frequency table is not something that one can purchase. This is a mathematical table that is used for statistics. One can find much more detail about frequency tables on the Wikipedia website.
You find the total of all the frequencies, N. Then the percentage for any frequency is 100*frequency/N.
bum fun fun
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.
To calculate the frequency density we will simply divide the frequency by the class width.
To calculate frequency when given a half-wavelength, you first find the full wavelength by doubling the half-wavelength value. Then, use the formula frequency = speed of wave / wavelength to find the frequency of the wave.
The length can be found by taking the larger number in the frequency group and subtracting it to find the range.
The energy of a photon of electromagnetic radiation is(Photon's frequency) times (Planck's Konstant) .
Frequency tables - particularly tidy ones - are usually rectangular in shape. So their angles are all 90 degrees.
* 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.
