Binary descriptive statistics

  • How do you describe binary data?

    In mathematics and in computing systems, a binary digit, or bit, is the smallest unit of data.
    Each bit has a single value of either 1 or 0, which means it can't take on any other value.
    Computers can represent numbers using binary code in the form of digital 1s and 0s inside the central processing unit (CPU) and RAM..

  • What are the three types of descriptive statistics?

    The 3 main types of descriptive statistics concern the frequency distribution, central tendency, and variability of a dataset..

  • What is a binary analysis in statistics?

    In statistics, binary data is a statistical data type consisting of categorical data that can take exactly two possible values, such as "A" and "B", or "heads" and "tails".
    It is also called dichotomous data, and an older term is quantal data.
    The two values are often referred to generically as "success" and "failure"..

  • What is an example of a binary variable in statistics?

    A binary variable is a variable that has two possible outcomes.
    For example, sex (male/female) or having a tattoo (yes/no) are both examples of a binary categorical variable.
    A random variable can be transformed into a binary variable by defining a “success” and a “failure”..

  • A binary variable is a categorical variable that can only take one of two values, usually represented as a Boolean — True or False — or an integer variable — 0 or 1 — where typically indicates that the attribute is absent, and indicates that it is present.
  • Binary outcomes are those that can take only one of two values, such as treatment failure or success, or mortality (dead or alive).
    Many trials have a binary outcome as one of the key measures used to compare treatments.

Summarising The Relationship Between Two Variables

Statistics become more interesting when we have two groups, and we will start with what is known as a 2x2 contingency table

Relative Risks Versus Odds Ratios

The odds ratio may not seem like an intuitively obvious statistic, but it has some useful properties

Odds Ratios and Case Control Studies

Case control and cohort studies relate exposure to some hazard to outcome in the form of disease or death
