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.

How many variables does a t test measure?
A t-test typically measures two variables: one categorical independent variable with two levels (groups) and one continuous dependent variable. It assesses whether there is a statistically significant difference in the means of the continuous variable between the two groups.
What is the difference between the logistic regression and regular regression?
in general regression model the dependent variable is continuous and independent variable is discrete type. in genral regression model the variables are linearly related. in logistic regression model the response varaible must be categorical type. the relation ship between the response and explonatory variables is non-linear.
What are the kinds of variables and their classification?
There are two main ways in which variables can be classified:They can be classified according to their functional role intocontrol,independent, ordependent.They can also be classified by the values that they can take, intoqualitative: categorical eg apple, banana, orangequantitative: numerical data. these can be further classified into discrete or continuous.
What are the possible variables?
Possible variables can include independent variables, which are manipulated in experiments, and dependent variables, which are measured outcomes. Other types include controlled variables, which are kept constant to ensure a fair test, and extraneous variables, which could unintentionally affect results. Additionally, categorical variables represent distinct groups, while continuous variables can take on a range of values. Identifying and managing these variables is crucial for accurate research and analysis.
What is correlation ratio?
The correlation ratio, often denoted as η (eta), measures the strength and direction of association between a continuous variable and a categorical variable. It quantifies how much variability in the continuous variable can be explained by the categorical variable. Unlike Pearson's correlation, which is limited to linear relationships between two continuous variables, the correlation ratio can capture relationships involving categorical data. It is particularly useful in statistical analysis to understand the influence of categorical factors on continuous outcomes.

What is the difference between continuous and discrete system?
The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.

What is analysis of covariance used for?
Analysis of covariance is used to test the main and interaction effects of categorical variables on a continuous dependent variable, controlling for the effects of selected other continuous variables, which co-vary with the dependent. The control variables are called the "covariates."

How are difference from independent variables?
Constants stays the same independent variables is the variable that is being manipulated
Variables that remain unchanged throughout an experiment are called?
Independent and Dependent Variables
Does a crosstabulation have to have both categorical and quantitative?
No, a crosstabulation does not have to include both categorical and quantitative variables. It is primarily used to summarize the relationship between two categorical variables. However, quantitative variables can be categorized into groups or bins to create a crosstabulation, but it's not a requirement.
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 categorical data?
Categorical data is the statistical data type consisting of categorical variables or of data that has been converted into that form, for example as grouped data.
What are the different variables during an experiment?
categorical variablesquantitative variablesordinal variablesthere are more common ones like...Controlled/constant variable-Variables that do not change at all!Manipulated/independent variable-Variables that change (intentionally) in order to see their effect on another variable.Responding/depending variable-Is measured quantitatively or qualitatively and is affected by the independent variables.Hope this helps.
