in statistics, if they say at least 5, than it means that it's x<5 or x>5?

At least 5 means 5 or more.

If X is at least 5, it is noted as X ≥ 5 or X is equal to or greater than 5.

I hope this helps a little more. Thanks for asking.

In statistics, when we say "at least 5", it means that the value is greater than or equal to 5. In other words, it includes the possibilities of being either equal to 5 or greater than 5.

To understand this concept, it's important to look at the symbols used in statistical notation. The symbol ">" means "greater than," while ">=" means "greater than or equal to."

For example, if we say "x ≥ 5", it means that x can be any value greater than or equal to 5. This includes numbers like 5, 6, 7, and so on. On the other hand, "x > 5" would exclude the value 5 itself, so it would only include numbers greater than 5, such as 6, 7, 8, and so forth.

Similarly, if we say "at least 5", it means the same as "x ≥ 5". It includes the value 5 and any value greater than 5. So, when you encounter the phrase "at least," you should think of it as being inclusive of the stated value.

In summary, "at least 5" in statistics means that x can be equal to 5 or any value greater than 5. It is denoted by "x ≥ 5".
