What does μ mean in statistics?
μ = ( Σ X i ) / not. The symbol μ represents the population mean. Symbol ΣX i is the sum of all X-scores present in the population (for example, in this case). 1 X 2 X 3 etc. The symbol N represents the total number of individuals or cases in the population.
What is the U symbol in statistics?
List of probability and statistics symbols

|N( μ ,σ 2 )||normal distribution||X ~ N(0,3)|
What is J in statistics?
A J-shaped distribution is a probability distribution roughly shaped like the letter J on one side, or its mirror image. These distributions typically have few observations at one end, very few in the middle, and many at the other end.
What does this probability symbol mean?
= P (A) • P (B | A) or P (B) * P (A | B) This straight line symbol | it does not mean separation! This symbol means conditional or given. For example, P (A | B) indicates the probability that event A occurs if event B occurs.
What is this symbol μ?
Micro (Greek letter μ or ancient symbol micro μ) is a unit prefix in the metric system, denoting a factor of 10. − 6 (one millionth). The prefix, approved in 1960, derives from the Greek μικρός (micros), which means “small”. The prefix symbol comes from the Greek letter μ (mu).
What do 3 stats mean?
In math, symbols that have a specific meaning in English can mean very specific and different things. … In mathematics, expression 3! is read as three factorials and is actually shorthand for multiplying several consecutive integers.
What is the symbol U in mathematics?
In set theory, the union (denoted by ∪) of a set of sets is the set of all elements of the set. This is one of the basic operations with which sets can be combined and related to each other.
What does SX mean in stats?
Sx = standard deviation of the sample. X. σ = population standard deviation.
What does J stand for in math?
The letter j is used to indicate that a number in electrical engineering is an imaginary number. See imaginary numbers. …
What does J mean?

What does ∩ mean in probability?
The probability of intersection of events A and B is denoted by P (A ∩ B). If events A and B are mutually exclusive, then P(A ∩ B) = 0. The probability that either event A or B occurs is equal to the probability that A and B come together.
What does PXY stand for?
The designation P(x | y) means P(x), if the event y occurred, then this designation is used in conditional probability. There are two cases when x and y are dependent or when x and y are independent.
