What does ∧ mean in math?

In logic, mathematics and linguistics, And ( ∧ ) is the truth-functional operator of logical conjunction; the and of a set of operands is true if and only if all of its operands are true.

Why mean is important?

The mean is essentially a model of your data set. It is the value that is most common. However, one of its important properties is that it minimises error in the prediction of any one value in your data set. That is, it is the value that produces the lowest amount of error from all other values in the data set.

What is mean explain with example?

Example: what is the mean of 2, 7 and 9? Add the numbers: 2 + 7 + 9 = 18. Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6. So the mean is 6. Note: there are other types such as Geometric Mean and Harmonic Mean.

What is mode explain with example?

A mode is defined as the value that has a higher frequency in a given set of values. It is the value that appears the most number of times. Example: In the given set of data: 2, 4, 5, 5, 6, 7, the mode of the data set is 5 since it has appeared in the set twice.
