Math Problem Statement
{12, 29, 6, 39, 17, 27, 50, 33, 49, 16, 22, 19, 24, 26, 31, 40} Using the data from Question 1 and the Frequency Distribution fill in the following. Use an x to indicate a column shaded and a 0 (zero) for an unshaded area.
Solution
To create a frequency distribution and fill in the columns based on the data provided, we need to follow these steps:
Step 1: Organize the Data
First, let's sort the data in ascending order:
{6, 12, 16, 17, 19, 22, 24, 26, 27, 29, 31, 33, 39, 40, 49, 50}
Step 2: Define the Classes
To create a frequency distribution, we need to define class intervals (or bins). Since the data spans from 6 to 50, let's consider the following intervals:
- Class Interval 1: 6 - 13
- Class Interval 2: 14 - 21
- Class Interval 3: 22 - 29
- Class Interval 4: 30 - 37
- Class Interval 5: 38 - 45
- Class Interval 6: 46 - 53
Step 3: Count the Frequency in Each Class Interval
Now, let's count the frequency of data points in each interval:
- 6 - 13: 6, 12 → 2 data points
- 14 - 21: 17, 19 → 2 data points
- 22 - 29: 22, 24, 26, 27, 29 → 5 data points
- 30 - 37: 31, 33 → 2 data points
- 38 - 45: 39, 40 → 2 data points
- 46 - 53: 49, 50 → 2 data points
Step 4: Fill in the Table with Shading Indication
Given the frequencies, we can now shade (x) or leave unshaded (0) the columns based on the frequency for each interval.
- Class Interval 1: 6 - 13 → Frequency = 2 → (xx000)
- Class Interval 2: 14 - 21 → Frequency = 2 → (xx000)
- Class Interval 3: 22 - 29 → Frequency = 5 → (xxxxx)
- Class Interval 4: 30 - 37 → Frequency = 2 → (xx000)
- Class Interval 5: 38 - 45 → Frequency = 2 → (xx000)
- Class Interval 6: 46 - 53 → Frequency = 2 → (xx000)
Shading Representation (x = Shaded, 0 = Unshaded)
Here's how the shading (x) or unshading (0) would look:
6 - 13 → xx000
14 - 21 → xx000
22 - 29 → xxxxx
30 - 37 → xx000
38 - 45 → xx000
46 - 53 → xx000

Relative Questions:
- How do you determine the number of class intervals to use in a frequency distribution?
- What are the advantages of using a frequency distribution to analyze data?
- How can you create a histogram based on this frequency distribution?
- What is the significance of the shape of the frequency distribution?
- How does the choice of class intervals affect the interpretation of the data?
Tip: When creating class intervals, ensure that they are mutually exclusive and collectively exhaustive, meaning every data point should fall into exactly one interval without overlap.
