Make a box-and-whisker plot of the data.
29, 21, 17, 10, 15, 27, 22, 30
i forget how you do this, can someone explain
D is the answer

hi
Hello! How can I assist you today?
Certainly! To create a box-and-whisker plot, also known as a box plot, you need to follow a few steps:
1. Arrange the data in ascending order:
10, 15, 17, 21, 22, 27, 29, 30
2. Find the minimum and maximum values:
The minimum value is 10, and the maximum value is 30.
3. Determine the median (the middle value of the dataset):
Since there are eight values, the median is the average of the two middle values: (21 + 22) / 2 = 21.5.
4. Calculate the lower quartile (Q1) and upper quartile (Q3):
Since there are eight values, Q1 is the median of the lower half of the dataset (10, 15, 17, 21): (15 + 17) / 2 = 16.
Q3 is the median of the upper half (22, 27, 29, 30): (27 + 29) / 2 = 28.
5. Determine the interquartile range (IQR):
The IQR is the difference between Q3 and Q1: 28 - 16 = 12.
6. Identify any outliers, if there are any:
To check for outliers, calculate the value of 1.5 times the IQR:
Lower Outlier Limit = Q1 - 1.5 * IQR
Upper Outlier Limit = Q3 + 1.5 * IQR
In this case, there are no values that fall below Q1 - 1.5 * IQR or above Q3 + 1.5 * IQR.
Now that we have the necessary information, let's create the box-and-whisker plot:
Minimum | Q1 | Median | Q3 | Maximum
10 | 16 | 21.5 | 28 | 30
The box in the plot represents the interquartile range (the span between Q1 and Q3), while the line inside it represents the median. The whiskers extend to the minimum and maximum values. If there were any outliers, they would be plotted outside the whiskers.
well its actually much easier if you click on link cuz that helped a lot (:
