In order to find Q1, you must first find Q2. Q2 is the median, or middle, for the entire set of given data. If the data set is 1, 2, 2, 3, 3, 4, 4 ,4, 5, 5, 6, 7, 7, then Q2 would be 4. Therefore, the first half of the data set is 1, 2, 2, 3, 3, 4. Q1 is the median for the first half of data. Since there are an even number of entries for the first half, the two middle numbers are averaged. Thus, 2+3=5, and 5/2=2.5. Q1 equals 2.5.

What does Q1 and Q3 mean in math?
maybe it is question 1 and question 2
What is a Q1 in math?
In math, Q1 refers to the first quadrant of a graph (which has a total of four quadrants), or the quadrant in the upper right hand corner. It contains both positive x and y values. This is especially useful in trigonometry when visualizing the sin(x) cos(x) and tan(x) functions.
Why do you find median?
You find the median to find the middle number
How do you find the base of the base shape to find the volume?
You find the length and height of the shape, them you find the volume
How do you find length and width of a rectangle?
you find the length and width by counting the numbers on the side to find the width and counting the numbers going across to find the length
