Questions & Step-by-Step Solutions
If the median of the data set {3, 1, 4, 2, 5} is x, what is the value of x?
Correct Answer: 3
Steps
Concepts
Step 1: Write down the original data set: {3, 1, 4, 2, 5}.
Step 2: Sort the data set in ascending order: {1, 2, 3, 4, 5}.
Step 3: Count how many numbers are in the sorted data set. There are 5 numbers.
Step 4: Since there is an odd number of values (5), the median is the middle number.
Step 5: Find the middle number in the sorted data set. The middle number is the 3rd number, which is 3.
Step 6: Therefore, the median (x) is 3.
Median
– The median is the middle value of a data set when it is ordered from least to greatest.
Data Sorting
– To find the median, the data set must be sorted in ascending order.
