Although much slower than RAM, ROM plays an important role because it dictates how much space your archive has. ROM, or Read-Only Memory, is usually more abundant than RAM in graphing calculators. Unless you're sitting a test where every second counts, you can get away with shopping from the lower end of the RAM scale. The amount of RAM in most graphing calculators varies from 26 KB to around 188 KB.Ĭalculators with less RAM take longer to compute, while those with more RAM are noticeably quicker.

Most graphing calculators come with enough RAM (Random Access Memory) to allow you to run multiple programs and store variables temporarily.

The interquartile range (IQR) is the range from the 25 th percentile to the 75 th percentile, or middle 50 percent, of a set of numbers. How to use the Interquartile Range Calculator:ġ) Enter each of the numbers in your set separated by a comma (e.g., 1,9,11,59,77), space (e.g., 1 9 11 59 77) or line break.Ģ) Click on the 'Calculate' button to calculate the interquartile range.

You can use this interquartile range calculator to determine the interquartile range of a set of numbers, including the first quartile, third quartile, and median.
