Math Problem Statement
what is the minimum, first quartile, median, third quartile, and max of these numbers 4.1, 5.2, 5.2, 6.0, 6.2, 6.3, 6.5
Solution
To find the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum for the given data set:
4.1, 5.2, 5.2, 6.0, 6.2, 6.3, 6.5, we follow these steps:
Step 1: Arrange the numbers in ascending order (already done):
4.1, 5.2, 5.2, 6.0, 6.2, 6.3, 6.5
Step 2: Calculate the values:
-
Minimum: The smallest number in the data set is 4.1.
-
First Quartile (Q1): Q1 is the median of the lower half of the data (below the median). In this case:
- The lower half of the data is 4.1, 5.2, 5.2.
- The median of this subset is 5.2 (since it's the middle number).
-
Median (Q2): Q2 is the middle value of the entire data set. Since there are 7 numbers, the median is the fourth value:
- The median is 6.0.
-
Third Quartile (Q3): Q3 is the median of the upper half of the data (above the median). The upper half is 6.2, 6.3, 6.5.
- The median of this subset is 6.3.
-
Maximum: The largest number in the data set is 6.5.
Final Summary:
- Minimum: 4.1
- First Quartile (Q1): 5.2
- Median (Q2): 6.0
- Third Quartile (Q3): 6.3
- Maximum: 6.5
