If the balls below are divided so that each column in the table contains an equal number, then how many balls will there be in each column?
Mean is the average (add all numbers ÷ count). Median is the middle value when arranged in order. Mode is the most frequently occurring number.
That's completely normal! Your average can be a decimal or fraction. For example, the average of 2, 3, and 4 is , but the average of 1, 2, and 3 is .
No! Addition is commutative, meaning you can add in any order. Whether you do 9+4+8 or 8+4+9, you'll get the same sum of 21.
Your average should be between the smallest and largest numbers. Since we have 4, 8, and 9, our average of 7 fits perfectly between 4 and 9!
The same process works! Add all the numbers together, then divide by however many numbers you have. The method stays exactly the same.
