## What if there is no mode?

It is possible for a set of data values to have more than one mode.

If there are two data values that occur most frequently, we say that the set of data values is bimodal.

If there is no data value or data values that occur most frequently, we say that the set of data values has no mode..

## What is R * in math?

In a different context, the notation R* denotes the reflexive-transitive closure of a (binary) relation R in a set X, i.e. the smallest relation in X that contains R and is reflexive as well as transitive. It is the union of all the non-negative powers of R, where R^0 = ∆_X, the diagonal relation in X and R^n =R•R•….

## What is mathematical language and symbols?

Mathematics is written in a symbolic language that is designed to express mathematical thoughts. … This article describes how mathematical thoughts, methods, and facts are expressed in symbolism. That is, it emphasizes how to read and write mathematics.

## What does μ mean?

Micro-Micro- (Greek letter μ or legacy micro symbol µ) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning “small”. … It is the only SI prefix which uses a character not from the Latin alphabet.

## 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.

## What does this symbol mean in maths?

< Less Than and > Greater Than. This symbol < means less than, for example 2 < 4 means that 2 is less than 4. This symbol > means greater than, for example 4 > 2. ≤ ≥ These symbols mean ‘less than or equal to’ and ‘greater than or equal to’ and are commonly used in algebra. In computer applications <= and >= are used.

## What is the symbol for mode?

## What is the mode formula?

Mean Median Mode Formula This is found by adding the numbers in a data set and dividing by how many numbers there are. … The mode is the value that occurs the most often in a data set, and the range is the difference between the highest and lowest values in a data set.

## What does U mean in statistics?

The symbol ‘μ’ represents the population mean. The symbol ‘Σ Xi’ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on. The symbol ‘N’ represents the total number of individuals or cases in the population.

## 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 AUB mean in probability?

P(A U B) is the probability of the sum of all sample points in A U B. Now P(A) + P(B) is the sum of probabilities of sample points in A and in B.

## What do the symbols mean in statistics?

By convention, specific symbols represent certain sample statistics. … x refers to a sample mean. 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 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.

## How mode is calculated?

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

## What is the symbol for the sample mean?

x̄The sample mean symbol is x̄, pronounced “x bar”.

## What does U mean in math?

The set made by combining the elements of two sets. So the union of sets A and B is the set of elements in A, or B, or both. The symbol is a special “U” like this: ∪ Example: Soccer = {alex, hunter, casey, drew}
