Final answer:
To construct a box-and-whisker plot for the given data, arrange the data in ascending order and find the median, lower quartile, and upper quartile. Plot these values on a number line and draw a box and whisker to represent the data.
Step-by-step explanation:
To construct a box-and-whisker plot for the given data, follow these steps:
- Arrange the data in ascending order: 310, 310, 310, 310, 320, 450, 460, 470, 500, 500, 505, 510, 520, 540, 580, 600, 650, 700, 700, 705, 705, 840, 870, 900, 1000, 1200, 1200, 1225, 1237.5, 1250, 1250, 1300, 1400, 1720, 2500, 3700, 3700, 3700, 3700, 3700.
- Find the median, which is the middle value of the data set. In this case, it is the 20th value, which is 705.
- Find the lower quartile, which is the median of the lower half of the data. In this case, it is the 10th value, which is 510.
- Find the upper quartile, which is the median of the upper half of the data. In this case, it is the 30th value, which is 1250.
- Plot the minimum value (310), the lower quartile (510), the median (705), the upper quartile (1250), and the maximum value (3700) on a number line.
- Draw a box, but the ends of the box at the lower quartile and the upper quartile, and draw a line (whisker) from the box to the minimum and maximum values.
