Can someone give me a website on examples of box-and whisker plots? I have to construct a plot for the following set of number:
0.16,0.08,0.27,0.20,0.22,0.32,0.25,0.18,0.28,0.27
I don't have a clue on how to do this. Thanks in advance.
I searched Google under the key words "box whisker plots" to get these possible sources:

In the future, to get the information more quickly, you can do similar searches yourself by using the appropriate key words.
I hope this helps. Thanks for asking.
To construct a box-and-whisker plot for the given set of numbers, you can follow these steps:
Step 1: Organize the data in ascending order:
0.08, 0.16, 0.18, 0.20, 0.22, 0.25, 0.27, 0.27, 0.28, 0.32
Step 2: Find the median (middle value) of the data. In this case, as there are 10 numbers, the median will be the average of the 5th and 6th numbers, which are 0.22 and 0.25. So the median is (0.22 + 0.25) / 2 = 0.235.
Step 3: Find the lower quartile (Q1) and upper quartile (Q3). Q1 is the median of the lower half of the data, and Q3 is the median of the upper half of the data. In this case, Q1 is the median of the first 5 numbers (0.08, 0.16, 0.18, 0.20, 0.22), which is 0.18. Q3 is the median of the last 5 numbers (0.25, 0.27, 0.27, 0.28, 0.32), which is 0.27.
Step 4: Find the minimum and maximum values. The minimum value is 0.08, and the maximum value is 0.32.
Step 5: Plot the box-and-whisker plot using the calculated values. Draw a number line and mark the minimum value, Q1, median, Q3, and maximum value. Connect Q1 and Q3 with a box, and draw vertical lines (whiskers) from the box to the minimum and maximum values.
Keep in mind that box-and-whisker plots can be visualized in various ways, so the specific layout and appearance may vary from source to source. It is helpful to refer to a specific website or resource for examples and illustrations.
