# AI-900: Gift Card Sales Forecasting Leveraging Regression in ML

Discover how regression models predict future gift card sales. Explore the role of regression in forecasting sales quantities for the upcoming month.

## Question

Which type of machine learning should you use to predict the number of gift cards that will be sold next month?

A. classification
B. regression
C. clustering

B. regression

## Explanation

For predicting the quantity of gift cards sold next month, the appropriate type of machine learning is option B: regression. Regression models are designed to forecast numerical values, making them suitable for predicting quantities or continuous variables like the number of gift cards sold in the upcoming month based on historical sales data.

In the most basic sense, regression refers to prediction of a numeric target. Linear regression attempts to establish a linear relationship between one or more independent variables and a numeric outcome, or dependent variable. You use this module to define a linear regression method, and then train a model using a labeled dataset. The trained model can then be used to make predictions.
