Averaging student test scores
Paste a column of grades straight from your gradebook or spreadsheet, separated by commas, spaces, or new lines, and instantly see the class mean. The median tells you the middle score so a few failing or perfect papers do not skew your read, and the min, max, and range show how spread out the marks really are before you finalize report cards.
Find the median of a dataset
When outliers distort the mean, the median is the more honest middle value. Drop your numbers in any order and the tool sorts them, then returns the median automatically, averaging the two central values for an even count. It is ideal for skewed figures like salaries, home prices, or response times where one extreme entry would otherwise pull the simple average off.
Sum and average a number list
Need the total and the average of the same list at once? Enter your values and read the sum and mean side by side, plus a live count confirming every number was picked up. Great for tallying receipt amounts, monthly expenses, or survey responses, it accepts decimals and negatives and ignores stray text, so messy pasted data still totals correctly.
