Read and construct side-by-side bar charts using accurate scales, totals and labels. In this lesson, focus on a statistical chart must represent each frequency honestly.
A statistical chart must represent each frequency honestly. Bars use a consistent scale, pictograms depend on their key, and pie-chart sectors convert category proportions into angles out of 360 degrees. For side-by-side bar charts, the final written answer should make that exact relationship visible rather than hiding it inside an unexplained result.
Side-by-side bar charts: A statistical chart must represent each frequency honestly. Read every category back from the finished chart and compare with the original table. Keep the side-by-side bar charts representation visible until the final line.
Edit a frequency table and watch the matching chart redraw with labelled scales and categories. Use the model to explain one change you notice while working on side-by-side bar charts.
Read every category back from the finished chart and compare with the original table. Write that check beside the final side-by-side bar charts answer.
Given information: Side-by-side bar charts — A table records cats 3, dogs 2, fish 4 and rabbits 2. Find the total frequency. Method choice: Identify the values, frequencies or categories that answer the question. Quote the numbers being compared and link the conclusion to the context. Calculation or reasoning: Add all frequencies: 3 + 2 + 4 + 2 = 11. Final answer: 11. Check: Quote the numbers being compared and link the conclusion to the context.

Given information: Side-by-side bar charts — A table records cats 3, dogs 2, fish 4 and rabbits 2. Find the total frequency. Method choice: use the side-by-side bar charts method and show each step with the stated values. Calculation or reasoning: Add all frequencies: 3 + 2 + 4 + 2 = 11. Final answer: 11. Check: substitute or compare with the original information to confirm the result fits the question.
Given information: Side-by-side bar charts — A table records cats 3, dogs 14, fish 14 and rabbits 10. Find the total frequency. Method choice: use the side-by-side bar charts method and show each step with the stated values. Calculation or reasoning: Add all frequencies: 3 + 14 + 14 + 10 = 41. Final answer: 41. Check: substitute or compare with the original information to confirm the result fits the question.
Check: Check the side-by-side bar charts result against the original information.
Given information: Side-by-side bar charts — A table records cats 3, dogs 13, fish 9 and rabbits 7. Find the total frequency. Method choice: use the side-by-side bar charts method and show each step with the stated values. Calculation or reasoning: Add all frequencies: 3 + 13 + 9 + 7 = 32. Final answer: 32. Check: substitute or compare with the original information to confirm the result fits the question.
Try explaining why each step works before checking the answer.
