Central Tendency Measures

What is the formula to calculate the mean of a set of numbers?

• Mean = (Sum of all numbers) * (Total count of numbers)

• Mean = (Sum of all numbers) + (Total count of numbers)

• Mean = (Sum of all numbers) / (Total count of numbers)

• Mean = (Sum of all numbers) - (Total count of numbers)
