# Inference vs. Prediction: What's the Difference?

Edited by Harlon Moss || By Aimie Carlson || Published on December 31, 2023
Inference is drawing conclusions from data or evidence, while prediction involves forecasting future events based on current information.

## Key Differences

Inference involves analyzing existing data to reach conclusions, often used in decision-making processes. Prediction, on the other hand, focuses on forecasting future events or outcomes based on current or past data.
In scientific research, inference helps in understanding the underlying mechanisms of observed phenomena. Prediction, in contrast, is used to test hypotheses about future occurrences or trends.
In data analysis, inference is used to draw conclusions about a population based on a sample. Prediction applies data analysis techniques to estimate future trends or outcomes.
In machine learning, inference involves understanding the model's decision-making process. Prediction, however, is the process of using a trained model to forecast future data points.
In statistics, inference refers to the process of estimating population parameters based on sample data. Prediction is about forecasting future data points based on existing statistical models.

#### Inference

(uncountable) The act or process of inferring by deduction or induction.

#### Prediction

The act of foretelling; also, that which is foretold; prophecy.
The predictions of cold and long winters.

#### Inference

(countable) That which is inferred; a truth or proposition drawn from another which is admitted or supposed to be true; a conclusion; a deduction.

#### Prediction

The act of predicting (as by reasoning about the future)

#### Inference

The act or process of inferring by deduction or induction.
Though it may chance to be right in the conclusions, it is yet unjust and mistaken in the method of inference.

#### Inference

That which inferred; a truth or proposition drawn from another which is admitted or supposed to be true; a conclusion; a deduction.
These inferences, or conclusions, are the effects of reasoning, and the three propositions, taken all together, are called syllogism, or argument.

#### Inference

The reasoning involved in drawing a conclusion or making a logical judgment on the basis of circumstantial evidence and prior conclusions rather than on the basis of direct observation

## FAQs

#### Can predictions always be accurate?

No, predictions are estimates and can be subject to errors.
