How do you make a box and whisker plot?
thahk you

First, order all of the data that you have from smallest to largest.

Then, from the data, you want to find the median, the quartiles, the maximum (highest value) and the minimum (smallest value)

To find the quartiles:

cut the data into quarters; then find the lower quartile (q1), middle quartile (median, q2), and the upper quartile (q3)

If the cuts are between 2 numbers, find the average of those numbers

ex.

2, 4, 4, 5, 6, 7, 8

^^^

q1q2 q3

Next, you would create a number line, the highest number on there being your maximum and the lowest your minimum, plotting the numbers in between (whether or not they were in your value set.)

Create a dot above the plot point of your upper and lower quartile, as well as your median.

Then, you are going to turn those dots into vertical lines and connect them all in a sort of square/rectangle separated into two pieces (each side doesn't have to be equal.)

As you did with your quartiles, create dots above your maximum and minimum.

Instead of creating rectangles and connecting them as done before, you should create a line that connects to the middle of the sides of the square/rectangle you created before.

To get a proper idea of what one should look like, google 'box and whisker plot example'

sorry i'm late. here is the explanation i gave someone else.

Step-by-step explanation:

First, you will need to determine the minimum value, lower quartile, median, upper quartile, and maximum value (Our 5 factors).

(example)

The minimum is 1

The lower quartile is 3

The median is 6

The upper quartile is 9

The maximum value is 12

Now we make a number line.

<>

0      1      2      3      4      5      6      7      8      9      10      11      12      13                                              

We have our number line finished, so we have to start labeling where are factors are located. I will label them with an "o" above each one.

      o              o                      o                      o                         o

<>

0      1      2      3      4      5      6      7      8      9      10      11      12      13    

 So, we got it all set. so now, we finish it off. We make a box, starting from the lower quartile and ending at the upper quartile like this. ( I could not make the full box, so I made a line above it.)

                      ||

      o              o                      o                      o                         o

<>

0      1      2      3      4      5      6      7      8      9      10      11      12      13      

Then, we make a whisker from the minimum to the lower quartile, then the upper quartile to the maximum like shown.

        ||

      o              o                      o                      o                         o

<>

0      1      2      3      4      5      6      7      8      9      10      11      12      13      

Then finally divide the box by the median.

       ||

                                               |      

      o              o                      o                      o                         o

<>

0      1      2      3      4      5      6      7      8      9      10      11      12      13  

                                                                           ^

                                                                           |

                                                                           |

                                                                           |

Your final product should look like the one above, except the fact that the box is NOT a line.

have a good day

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
