statement about a future event
A sentence or idea that says what you think will happen in the future.
用法模式：
[someone] makes a prediction about [something]
常见错误：
Learners often say *do a prediction* instead of the correct *make a prediction*. Another common mistake is using *prediction* when they mean a simple *guess*; *prediction* usually suggests some reason or knowledge, while *guess* can be more random.
近义词

The work or science of saying what will happen in the future, using information and rules.

output from a predictive model
The answer that a computer model gives when it tries to say what the result will be.
用法模式：
a model’s prediction of [value/outcome]
