What else can I help you with?
To evaluate a variable expression you must do what to values for the variable?
You must substitute values for the variable.
What is a boolean variable?
A Boolean variable is a variable from Boolean algebra having one of only two values.
What range of values was used for your independent variable?
From the minimum value of the independent variable to its maximum.
What does solve the equation mean?
Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.
How are the independent and dependent variables related?
Independent variables can take values within a given boundary. The dependent variable will take values based on the independent variable and a given relationship at which the former can take its values.
Difference between dummy and categorical variable?
A dummy variable assumes a value of either 0 or 1. A categorical variable assumes one of a usually small number of values. For example, a categorical variable might assume the values 'F' or 'M' for female or male.
What is the difference between continuous and categorical independent variables?
A categorical variable (also known as a discrete variable) is one whose range is countable; e.g. the variable answ has values [yes, no, not sure]. answ is a categorical variable with range 3.A continuous variable is one which is not categorical; e.g. weight is a continuous variable which can take any value between 0 and 1000 kg (say) for a human being.
Is a score on a test a categorical variable?
No, a score on a test is not a categorical variable; it is a quantitative variable. Test scores represent measurable quantities, typically on a numerical scale, allowing for a range of values and mathematical operations. Categorical variables, on the other hand, represent distinct categories or groups without inherent numerical value.
When the measurement of a variable has a categoryvariable value for every unit of analysis observed the categoriesvariable values are said to be?
They are said to be categorical.
What are categorical variables?
Categorical variables take on a limited and at times a fixed number of value possibilities. If in fields such as Compute Science or Mathematics, they are referred to as enumerated types. In some cases possible values of a variable may be classified as levels.
David asks each of his familty members what their favorite vegetable is list four possible values for this variable?
david asks each of his family members what their favorite vegatable is ?is he collecting data on a numerical or categorical variable?
Do graph tables include numerical data?
Yes, graph tables typically include numerical data, as they are designed to represent quantitative information visually. These tables often display values that can be graphed, such as measurements, counts, or statistics, allowing for easier interpretation of trends and relationships. Additionally, they may include categorical data that complements the numerical values for context.
Is a persons height categorical or continuous?
A person's height is considered a continuous variable because it can take on an infinite number of values within a given range. Heights can be measured with precision and can vary by small increments, such as in inches or centimeters. In contrast, categorical variables represent distinct categories or groups without inherent numerical values.
What is a category variable?
A category variable, also known as a categorical variable, is a type of variable that represents distinct categories or groups rather than numerical values. These variables can be nominal, with no inherent order (e.g., colors or types of animals), or ordinal, where there is a meaningful order among categories (e.g., ratings like "poor," "average," "excellent"). Categorical variables are often used in statistics and data analysis to classify data and perform group comparisons.
How do you compute probabilities of a standard normal random variable?
You need to determine the area under the curve between the values in question. This is easy to do because there are tables that give the area values.
What is a factor set?
A factor set, often used in mathematics and statistics, refers to a collection of values or elements that can be used to create factors in a certain context, such as in analysis of variance (ANOVA) or experimental design. In this context, a factor is a categorical variable that can influence the outcome of an experiment or study. Factor sets help in organizing the levels of these categorical variables for better understanding and analysis of their effects on the dependent variable.
What is an ordered variable?
An ordered variable, also known as an ordinal variable, is a type of categorical variable where the values have a meaningful order or ranking but do not have a consistent scale between them. For example, survey responses such as "satisfied," "neutral," and "dissatisfied" can be ranked, but the differences between these categories are not quantifiable. Ordered variables are useful in statistical analyses where the order matters, but the exact differences do not.
