Bar Graph + World Comparison Lab

What you will create

You will make a bar graph with categories on the x-axis and values on the y-axis. You will compare your data to a partner and a world sample, then explain the pattern in complete sentences.

Choose labels

Click or drag categories into the x-axis boxes.

Enter values

Add your numbers and partner numbers.

Add world data

Use the sample data for comparison.

Build y-values

Use blocks or buttons to build bars.

Explain

Write what the graph shows.

Student goal

I can create a bar graph and use evidence to compare my data with partner and world sample data.

Important note

The world data is a classroom practice sample, not official research data. It is included so students can practice comparing three data sets.

My + Partner Data

Use the Category Bank to fill the x-axis labels. Then enter your values and your partner’s values.

Use sample categories Add row Clear category labels Clear my values Clear partner values

Category Bank: Click a category to place it in the next empty x-axis box. Or drag a category into any category box.

X-Axis Category Label	My y-value	Partner y-value	World y-value	Remove

Next step: calculate the statistics yourself

The next tab will sort each data set for you. Then you will calculate the mean, median, mode, and range using simple guided steps.

No answer reveal: This activity sorts the numbers, but students still do the calculations.

Calculate Mean, Median, Mode, and Range

The computer sorts the numbers for you. You still do the math. Use the sorted list, follow the steps, and type your final answers.

Simple reminder: Mean = add and divide. Median = middle. Mode = repeats most. Range = greatest minus smallest.

My Data Calculations

Sorted my data

Enter values first.

1. Mean

Mean = sum ÷ count

Add all values. Count how many values. Then divide.

2. Median

Use the sorted list. Find the middle value. If there are two middle values, add them and divide by 2.

3. Mode

Look for the value that repeats the most. If no value repeats, write “no mode.”

4. Range

Range = greatest − smallest

Use the sorted list to find the smallest and greatest values.

Partner Data Calculations

Sorted partner data

Enter values first.

1. Mean

Mean = sum ÷ count

Add all values. Count how many values. Then divide.

2. Median

Use the sorted list. Find the middle value. If there are two middle values, add them and divide by 2.

3. Mode

Look for the value that repeats the most. If no value repeats, write “no mode.”

4. Range

Range = greatest − smallest

Use the sorted list to find the smallest and greatest values.

World Sample Calculations

Sorted world sample data

Enter or auto-fill world values first.

1. Mean

Mean = sum ÷ count

Add all values. Count how many values. Then divide.

2. Median

Use the sorted list. Find the middle value. If there are two middle values, add them and divide by 2.

3. Mode

Look for the value that repeats the most. If no value repeats, write “no mode.”

4. Range

Range = greatest − smallest

Use the sorted list to find the smallest and greatest values.

World Sample Data

Choose world sample values to compare with your categories. These are classroom practice numbers.

Auto-fill matching world values Add all world sample categories Clear world values

Tip: For the clearest graph, use categories that match the world sample labels, such as Sleep hours, Screen minutes, Creative minutes, Homework minutes, Outside minutes, and Cups of water.

Interactive Graph Builder

Your x-axis labels are the categories. Build the y-values by typing values or using the + / − buttons. The stack blocks show how the bars are built.

Each stack block equals

Sort categories

My data Partner data World sample

Build the y-values with blocks

Use the buttons to add or subtract one stack block at a time. This is a hands-on way to build the bar heights.
