Lotto 6/49 「大樂透」 Quartile and Range Trend

Box Plot of Lotto Draw Results Over Time

The chart below displays the statistical distribution, spread, or variability of winning lotto numbers across multiple draws over time. Each box represents the middle 50% of numbers (from the first quartile to the third quartile), while the line inside the box marks the median winning number for that period. The “whiskers” extend to the minimum and maximum numbers drawn, and any points outside these whiskers indicate unusually low or high results relative to other draws. By tracking how the quartiles and range shift over time, the chart provides insight into the variability and spread of winning numbers, which can be used to visually assess the randomness and consistency of lotto draws.
