You can use the free Mathway calculator and problem solver below to practice Algebra or other math topics. Since there is an even number of values, we need the mean of the middle two values to find the first quartile:. Basic math formulas Algebra word problems. Suppose that the box-and-whisker plots below represent quiz scores out of 25 points for Quiz 1 and Quiz 2 for the same class. The values 3, 5, 7, and 8 are to the left of 12, and 13, 14, 18, and 21 are to the right of From our Example 1’s on the previous pages, we see that the five-number summary is: Similarly, the upper half of the data is:

K tests, GED math test, basic math tests, geometry tests, algebra tests. Prolbem, we put the values into increasing order: A box-and-whisker plot or boxplot is a diagram based on the five-number summary of a data set.

Draw a line from the smallest value 5 to the left side of the box and draw a line from the right side of the box to the biggest value We would conclude that as a whole the students in are less prepared than the students in First, we write data in increasing order: Join the lines for the lower quartile and the upper quartile to form a box.

Similarly, the upper half of the data is: The key values are called a five-number summarywhich consists of the minimum, first quartile, median, third quartile, and maximum.
