入力例：「5, 7, 3」または「5 7 3」または1行に1つの数値
結果
The average of all values. Add all numbers and divide by the count.
The middle value when numbers are sorted. If there's an even count, it's the average of the two middle values.
The value(s) that appear most frequently. There can be multiple modes or no mode at all.
The difference between the largest and smallest values. Shows the spread of data.
統計用語の定義
平均
The arithmetic mean is calculated by adding all values in a data set and dividing by the number of values. It represents the central tendency of the data.
中央値
The median is the middle value in a sorted data set. For an even number of values, it is the average of the two middle numbers. It is less affected by outliers than the mean.
最頻値
The mode is the value that appears most frequently in a data set. A data set may have one mode, multiple modes, or no mode if all values appear with equal frequency.
範囲
The range measures the spread of data by calculating the difference between the maximum and minimum values. A larger range indicates more variability in the data.
