Average Calculator
Mean, median, min, max & range · 평균 계산기
Paste a data set to get the mean (average), median, sum, min, max, and range — then drill the concepts in the live tool.
How to use this calculator
- Type or paste your numbers, separated by commas, spaces, or new lines.
- Press Calculate (or Ctrl/Cmd + Enter) for every summary statistic at once.
- The mean is the everyday average (sum ÷ count); the median is the middle value.
숫자를 쉼표·공백·줄바꿈으로 구분해 입력하고 Calculate(또는 Ctrl/Cmd+Enter)를 누르면 평균·중앙값·합·최솟값·최댓값·범위가 한 번에 나옵니다. 평균은 합÷개수, 중앙값은 가운데 값입니다.
Mean vs median — which average?
The mean uses every value, so a single outlier can pull it far from the typical value; the median ignores extremes and better describes skewed data like incomes or prices. Report the mean for roughly symmetric data and the median when a long tail or outliers are present. For the full treatment see the mean guide and the median guide.
평균은 모든 값을 쓰므로 이상치 하나에 크게 흔들리고, 중앙값은 극단값을 무시해 치우친 데이터(소득·가격)를 더 잘 나타냅니다. 자세한 내용은 평균·중앙값 문서를 참고하세요.
Worked example
For 4, 8, 15, 16, 23, 42 (n = 6): the sum is 108, so the mean is 108 / 6 = 18. Sorted, the two middle values are 15 and 16, so the median is (15 + 16)/2 = 15.5. The range is 42 − 4 = 38. Press Try an example above to load this set.
4, 8, 15, 16, 23, 42 (n=6): 합 108 → 평균 18, 가운데 두 값 15·16 → 중앙값 15.5, 범위 42−4 = 38.
Frequently asked questions
How do I calculate the average? Add all the values, then divide by how many there are: mean = sum ÷ count.
Is the average the same as the mean? In everyday use, yes — "average" usually means the arithmetic mean. The median and mode are other kinds of average.
When should I use the median instead? When the data are skewed or contain outliers, since the median is not dragged by extreme values.
평균은 모든 값을 더해 개수로 나눕니다(합÷개수). 일상에서 "평균"은 보통 산술평균을 뜻하며, 중앙값·최빈값도 평균의 일종입니다. 치우치거나 이상치가 있으면 중앙값이 낫습니다.
