What should you ensure when adding numbers to find an average?

When calculating an average, it is crucial to add the numbers in a systematic manner to minimize the likelihood of errors. A systematic approach means following a consistent method when entering and summing the numbers, which reduces the risk of mistakes often associated with mental math or random entry. This is especially important in disciplines like law enforcement, where precise calculations can impact decision-making and reporting.

Using a systematic method might involve writing down each number clearly, organizing them in a column for addition, or checking off each number as it is added. This careful process ensures that all values are accounted for correctly, leading to an accurate average.

The mention of whole numbers or avoiding decimals does not affect the fundamental process of averaging, as averages can indeed be calculated with decimals or fractions and are often needed in precise measurements. Additionally, while using a calculator can aid accuracy, it is the methodology of adding that primarily influences the correctness of the final average. Thus, focusing on a systematic approach is essential for accuracy in finding averages.
