Hello viewers!
My name is Sunday, and in today’s tutorial on AllCBTs, we’re solving one of the most frequently asked questions in NABTEB Economics 2025. This is an essay-style question based on data analysis — so follow along carefully step by step.

Problem Background

We’re provided with data showing the number of bad oranges (x) found in baskets from a farm. Based on this dataset, we’re required to:

1. Create a frequency table
2. Generate the cumulative frequency distribution
3. Construct a histogram
4. Draw a frequency polygon

Let’s go through these one by one.

Step 1: Frequency Table

Frequency Distribution

This table shows how many times each category of bad oranges appeared in the sample.

How We Calculated It

From the dataset:

• Zero appears 6 times
• One appears 8 times
• Two appears 6 times

This gives us the frequency for each number of bad oranges found in the baskets.

This answers Question A1 — forming the frequency table from raw data.

Step 2: Cumulative Frequency Distribution

We now add up the frequencies sequentially:

This helps show how the total number of observations accumulates as x increases.

Step 3: Histogram & Frequency Polygon

To visualize the data:

• Histogram: Draw bars to represent the frequency for each x-value.
• Frequency Polygon: Plot points above the midpoints of the bars, then connect them with straight lines.

These tools help communicate data trends effectively in a visual format.
