The third quartile (Q 3) is the 75th percentile where lowest 75% data is below this point. It is known as the upper quartile, as 75% of the data lies below this point. [1] Along with the minimum and maximum of the data (which are also quartiles), the three quartiles described above provide a five-number summary of the data.
75 is a self number because there is no integer that added up to its own digits adds up to 75. [1] It is the sum of the first five pentagonal numbers , and therefore a pentagonal pyramidal number , as well as a nonagonal number .
Note that the middle five of the seven numbers are very nearly the same as for the seven number summary, above. The addition of the deciles allow one to compute the interdecile range , which for a normal distribution can be scaled to give a reasonably efficient estimate of standard deviation, and the 10% midsummary , which when compared to the ...

The ratio of width to height of standard-definition television. In mathematics, a ratio (/ ˈ r eɪ ʃ (i) oʊ /) shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
In the United Kingdom, proof is 1.75 times the number (expressed as a percentage). [23] [20] For example, 40% alc/vol is 80 proof in the US and 70 proof in the UK. However, since 1980, alcohol proof in the UK has been replaced by alc/vol as a measure of alcohol content, avoiding confusion between the UK and US proof standards. [citation needed]

That means its brightness in HSB color notation is less than 100%; about 30 of the base colors are fully bright. The four variants (1...4) have rounded brightness values of 100%, 93%, 80% and 55%, respectively.
