## Covariance

Covariance is a measure of how two variables change together. It is calculated as the variance of the product of the two variables divided by the product of their standard deviations.

## Continuous Variable

A continuous variable is a mathematical construct that can take on any value within a given range. In contrast, discrete variables can only take on specific, discrete values. Continuous variables are important…

## Confusion Matrix

Confusion Matrix: A confusion matrix is a table that is used to summarize the performance of a classification algorithm. The table shows how many times each class was predicted by the algorithm and …

## Cross Validation

Cross Validation: Cross validation is a technique used in data science to improve the accuracy of predictions. It works by splitting the data into two sets, a training set and a testing set. The training set is …

## Confidence Interval

Confidence Interval: A range of values that is calculated based on sample statistics and is used to measure how accurate a prediction made by a model is likely to be.

## Clustering

Clustering: Clustering is a technique used in data science to group similar items together. This can be useful for organizing data and understanding relationships between different groups of data.

## Classification

Classification: The task of classification is to take a set of observations and assign one of a pre-determined number of classes to each observation. Classification is a technique used in data science to …
