Considering this from a physics point of view, age or the progression of time d*/dt is continuous. I know I am continuously aging. Of course when we speak of our age we tend to jump and ignore fractional changes right? One day we're 28 and stay that way for 364 days, then bang we're 29. No one says well I'm 28.6 years old. Some seem to be stuck at 29, until they have to be honest about it and there is an abrupt change to say 40.
What else can I help you with?
What is the difference between a factor and a covariate for multinomial logistic reg?
It is just a factor or categorical variable. On the other hand for instance, If your age is continuous (rather than age brackets) then it would be a covariate. If your age is given as age-brackets, then it wont be covariate.
Is number of children a continuous variable or categorical variable?
Neither. It is a discrete variable.
Is percent a discrete or continuous variable?
It depends how we have computed %age. By and large, percentage is a summary statistic. Its a categorical variable (may be nominal or ordinal). That way its a discrete. In case of assay or yield computations it becomes a continuous variable. Naresh K Chawla nkchawla@gmail.com
Is age a categorical variable?
Age is acontinuousvariable because it can bemeasured with numbers. A categorical variable deals with nominal variables example male or female, political view, etc
Can the median be used to descibe both numerical data and categorical data?
It can be used to describe continuous or discreet data but not categorical or ordered data, unless that data is also numercal which is very unlikely
What type of variable continuous discrete or categorical is years of experience?
continuous discrete
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.
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.
Is the independent variable continuous or categorical?
To determine whether the independent variable is continuous or categorical, you need to consider its nature. A continuous variable can take on an infinite number of values within a given range, such as height or temperature. In contrast, a categorical variable consists of distinct categories or groups, such as gender or type of cuisine. The classification depends on how the variable is measured and the context of the study.

Neither. It is a discrete variable.
What type of variable is age groups?
Age groups are typically considered categorical variables, specifically ordinal variables. This is because age groups represent distinct categories (e.g., 0-18, 19-35, 36-55, etc.) that have a meaningful order but do not have a consistent interval between them. While the age itself is a continuous variable, when categorized into groups, it loses some of that continuity and is treated as categorical.
Can categorical data be continuous?
No, categorical data cannot be continuous. Categorical data consists of distinct categories or groups, such as colors, brands, or yes/no responses, where values represent different classifications rather than quantities. Continuous data, on the other hand, can take any value within a range and is measured on a scale, such as height or temperature. Thus, the two types of data are fundamentally different in nature.
Is BMI rating a categorical or continuous?
BMI (Body Mass Index) is considered a continuous measure because it calculates a numeric value based on an individual's weight and height. However, it is often used in a categorical manner to classify individuals into categories such as underweight, normal weight, overweight, and obese based on specific BMI ranges. Thus, while the underlying data is continuous, its application in health assessments can be categorical.
