Math Problem Statement
Solution
To find the 5-number summary for the data given, let’s go through each component. The 5-number summary consists of:
- Minimum: The smallest value in the data set.
- Q1 (First Quartile): The median of the lower half of the data (25th percentile).
- Median (Q2): The middle value of the data set (50th percentile).
- Q3 (Third Quartile): The median of the upper half of the data (75th percentile).
- Maximum: The largest value in the data set.
The provided data, in ascending order, is:
Step-by-Step Solution:
- Minimum:
- Maximum:
To find the quartiles, we’ll use the following steps:
-
Median (Q2): Since there are 14 values, the median will be the average of the 7th and 8th values.
-
First Quartile (Q1): The first quartile is the median of the lower half (first seven values: ).
-
Third Quartile (Q3): The third quartile is the median of the upper half (last seven values: ).
Final 5-Number Summary:
- Minimum:
- Q1:
- Median (Q2):
- Q3:
- Maximum:
So, the correct answers should be:

- How do you find quartiles for an odd number of data points?
- What is the interquartile range, and how is it calculated?
- How do outliers affect the five-number summary?
- How can you use a boxplot to represent the five-number summary visually?
- What is the difference between quartiles and percentiles?
Tip: Always arrange your data in ascending order before finding the five-number summary.
