In a dataset, what do the columns represent?1 pointObservationsFeaturesVariable TypeIndependent Variables

In a dataset, the columns typically represent different attributes or characteristics of the data being analyzed. Here's a breakdown of the options provided:

1. Observations: Each row in a dataset corresponds to an observation or a single instance of data. Observations represent the individual data points collected.

2. Features: The columns of a dataset are often referred to as features. Features are the input variables or characteristics used to describe each observation. They can include numerical values, categorical data, or other types of information.

3. Variable Type: This refers to the nature of the data within the columns, such as whether it is categorical (nominal, ordinal) or numerical (continuous, discrete). Each column's variable type helps in understanding how the data can be used and analyzed.

4. Independent Variables: These are variables in a dataset that are manipulated to observe their effect on dependent variables. Columns representing independent variables are often used in predictive modeling.

In summary, columns in a dataset fundamentally represent features or attributes of the observations, forming the basis for further analysis or modeling.
