Random variables are usually written in upper case Roman letters, such as or and so on. Random variables, in this context, usually refer to something in words, such as "the height of a subject" for a continuous variable, or "the number of cars in the school car park" for a discrete variable, or "the colour of the next bicycle" for a categorical variable.
In symbolic form, the number of nucleons is denoted as a superscripted prefix to the chemical symbol (for example 3 He, 12 C, 13 C, 131 I, and 238 U). The letters m or f may follow the number to indicate metastable or fission isomers, as in 58m Co or 240f Pu. Subscripts and superscripts can also be used together to give more specific ...
¯ = sample mean of differences d 0 {\displaystyle d_{0}} = hypothesized population mean difference s d {\displaystyle s_{d}} = standard deviation of differences
3. Sometimes denotes the top element of a bounded lattice (previous meanings are specific examples). 4. For the use as a superscript, see ⊤. ⊥ 1. denotes the logical predicate always false. 2. Denotes also the truth value false. 3. Sometimes denotes the bottom element of a bounded lattice (previous meanings are specific examples). 4.
Mathematical notation consists of using symbols for representing operations, unspecified numbers, relations, and any other mathematical objects and assembling them into expressions and formulas. Mathematical notation is widely used in mathematics , science , and engineering for representing complex concepts and properties in a concise ...
A superscript is understood to be grouped as long as it continues in the form of a superscript. For example if an x has a superscript of the forma+b, the sum is the exponent. For example: x 2+3, it is understood that the 2+3 is grouped, and that the exponent is the sum of 2 and 3. These rules are understood by all mathematicians.
The most common superscript digits (1, 2, and 3) were included in ISO-8859-1 and were therefore carried over into those code points in the Latin-1 range of Unicode. The remainder were placed along with basic arithmetical symbols, and later some Latin subscripts, in a dedicated block at U+2070 to U+209F. The table below shows these characters ...
Superscripts and Subscripts is a Unicode block containing superscript and subscript numerals, mathematical operators, and letters used in mathematics and phonetics. The use of subscripts and superscripts in Unicode allows any polynomial , chemical and certain other equations to be represented in plain text without using any form of markup like ...
