A histogram displays the distribution of numeric data by grouping values into intervals (bins) and showing how many data points fall into each — revealing the overall shape of the data.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1Data 12,15,18,22,25,29,33,35,40 with bins of 10; frequency of 20-30:
2Using the same data, frequency of 30-40:
3Using the same data, frequency of 10-20:
4A histogram with two separate peaks is:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5A histogram groups data into .
6In the data, the 20-30 bin has frequency .
7Data 12,15,18,22,25,29,33,35,40; bins of 10. Find the frequency for 20-30.
8Using the same data and bins, find the frequency for 30-40.
9Using the same data and bins, find the frequency for 10-20.
