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.
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.
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.
Non-categorical data, also known as continuous or quantitative data, includes variables that can take on a wide range of values. Examples include height (measured in centimeters), weight (in kilograms), temperature (in degrees Celsius or Fahrenheit), and time (in seconds). These data types allow for mathematical operations and can be measured on a scale, unlike categorical data, which is limited to distinct categories or groups.
The graph that is most used for categorical data is the pie chart. Bar graphs have also been used for categorical data.
Categorical data varies when there are a variety of different categories.
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
No, a histogram is not suitable for categorical data because it represents the distribution of continuous or discrete numerical data through bins. Instead, bar charts are used for categorical data, as they effectively display the frequency of each category. Histograms show how data falls into ranges, while bar charts highlight distinct categories.

Yes, a zip code is an example of categorical data. It represents a specific geographical area and is used to categorize locations rather than quantify them. While zip codes can be associated with certain numerical values, they do not have inherent mathematical meaning, making them categorical rather than continuous data.
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.

It means numerical data which can hold any value . For instance, human height is continuous. There is no set of allowable heights. It can be any number. In contrast, human sex (i.e male or female) is categorical data, because there are only two possible values.
