Common Mistakes to Avoid
Counting empty entries as zero
Fix: Only count actual numbers. Blank or non-numeric entries should be ignored, not treated as zero.
Dividing by the wrong count
Fix: The denominator is the number of values, not the largest value or the number of digits.
Confusing average with median
Fix: The average is the sum divided by the count. The median is the middle value when sorted. They are only equal in symmetric data.
