What is the mean of 2, 4, 4, 5, 5, 5 rounded to two decimals?

Explanation:
Mean is found by adding all the values and dividing by how many numbers there are. Adding 2, 4, 4, 5, 5, and 5 gives 25, and there are 6 numbers, so the mean is 25/6 = 4.1666…. Rounding to two decimals uses the third decimal: since it’s 6, we round the second decimal up. That makes the result 4.17.
