What do the symbols mean in probability?
Definitions and Notation The conditional probability of Event A, given Event B, is denoted by the symbol P(A|B). The complement of an event is the event not occurring. … The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B) = 0.
What does or mean in statistics?
In probability, there’s a very important distinction between the words and and or. And means that the outcome has to satisfy both conditions at the same time. Or means that the outcome has to satisfy one condition, or the other condition, or both at the same time.
What is the symbol for the sample mean?
x̄The sample mean symbol is x̄, pronounced “x bar”.
What do Venn diagram symbols mean?
Venn diagrams are comprised of a series of overlapping circles, each circle representing a category. To represent the union of two sets, we use the ∪ symbol — not to be confused with the letter ‘u. ‘ … This diagram represents the union of A and B which we notate as A ∪ B.
What does ∩ mean?
Intersection of SetsDefinition of Intersection of Sets: Intersection of two given sets is the largest set which contains all the elements that are common to both the sets. The symbol for denoting intersection of sets is ‘∩’. …
What is the sample mean in statistics?
A sample mean refers to the average of a set of data. The sample mean can be used to calculate the central tendency, standard deviation and the variance of a data set. The sample mean can be applied to a variety of uses, including calculating population averages.

How do you write statistical symbols?
On the Insert tab, in the Symbols group, click the arrow under Equation, and then click Insert New Equation. Under Equation Tools, on the Design tab, in the Symbols group, click the More arrow. Click the arrow next to the name of the symbol set, and then select the symbol set that you want to display.
What is the U symbol in math?
In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other. For explanation of the symbols used in this article, refer to the table of mathematical symbols.
What does P mean in statistics?
What Is P-Value? In statistics, the p-value is the probability of obtaining results as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct. … A smaller p-value means that there is stronger evidence in favor of the alternative hypothesis.
What is S in stats?
Sample Statistics s refers to the standard deviation of a sample. s2 refers to the variance of a sample. p refers to the proportion of sample elements that have a particular attribute.
What does C stand for in probability?
By ComplementThe complement of an event is the subset of outcomes in the sample space that are not in the event. A complement is itself an event. The complement of an event A is denoted as A c A^c Ac or A′. An event and its complement are mutually exclusive and exhaustive.
