How to fill out a1q4-17 quartiles and box

How to fill out a1q4-17 quartiles and box:

1. Start by organizing the data: Gather the set of numbers or values that you want to calculate the quartiles and box plot for. Make sure the data is numerical.
2. Arrange the data in ascending order: Put the data in numerical order from smallest to largest. This will make it easier to determine the quartiles.
3. Calculate the first quartile (Q1): The first quartile divides the data into the lower 25% range. To find it, you can use the following formula: Q1 = (n + 1) / 4, where n is the number of data points. If the result is a whole number, take the value at that position in the sorted data. If it's a decimal, find the two values surrounding it and calculate the average.
4. Calculate the second quartile (Q2 or median): The second quartile is the midpoint of the entire data set. It divides the data into the lower 50% and upper 50% ranges. If the number of data points is odd, simply take the middle value. If it's even, find the two values in the middle and calculate their average.
5. Calculate the third quartile (Q3): The third quartile divides the data into the upper 25% range. You can use the formula Q3 = (3n + 1) / 4 to find it. Again, if the result is a whole number, take the value at that position. If it's a decimal, find the two values surrounding it and calculate the average.
6. Create the box plot: A box plot visually represents the quartiles and additional information about the data set. Draw a number line and mark the appropriate values for Q1, Q2 (median), and Q3. Then, draw a box from Q1 to Q3 and a vertical line in the box to represent the median. Finally, extend lines or "whiskers" from the box to the minimum and maximum data points.
