The intervals must be of EQUAL SIZE.
That is, if I have a data set of numbers ranging from 1 to 20, I might create 4 intervals of 5 each, because 20 divides by 5 evenly. So I would get a table:
---------------------------------------------
| Interval | Tally | Frequency |
---------------------------------------------
| 1-5 | | |
| | | |
| 6-10 | | |
| | | |
| 10-15 | | |
| | | |
| 15-20 | | |

What is the ratio of the diameter of a round table top to the diameter of the table's base on a pedestal table?
According to eHow, your base area must support at least 1/3 of the table top area.
How do you do a steam and leaf plot?
Stem-and-leaf plots are a method for showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values, or you can use a stem-and-leaf plot and let the numbers show the same information.For instance, suppose you have the following list of values: 12, 13, 21, 27, 33, 34, 35, 37, 40, 40, 41. You could make a frequency distribution table showing how many tens, twenties, thirties, and forties you have:FrequencyClassFrequency10 - 19220 - 29230 - 39440 - 493You could make a histogram, which is a bar-graph showing the number of occurrences, with the classes being numbers in the tens, twenties, thirties, and forties. (The shading of the bars in a histogram isn't necessary, but it can be helpful by making the bars easier to see, especially if you can't use color to differentiate the bars.)The downside of frequency distribution tables and histograms is that, while the frequency of each class is easy to see, the original data points have been lost.You can tell, for instance, that there must have been three listed values that were in the forties, but there is no way to tell from the table or from the histogram what those values might have been.
How do you know that 7 must be a factor of each multiple of 7?
Because it's the seven times table
How the 40 meters wave length is equal to 7 mhz frequency?
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
