Read and notice

Read the title, labels, units and source before making a claim.
Tables organise data in rows and columns. Bar charts compare categories.
In a process diagram, arrows can show order rather than quantities. Read the caption and labels together.
Frequency tells how many people or items are in a group.
Calculate a percentage with (part ÷ whole) × 100.
Describe only what the data supports. A pattern alone does not prove a cause.

Practice only: library visits by 20 learners in one week
Visits per learner	Number of learners
0 visits	5
1 visit	9
2 visits	4
3 visits	2
Total	20

In this practice sample, nine of the twenty learners made one library visit. That is the largest group. Four learners made two visits: (4 ÷ 20) × 100 = 20%. The table does not measure grades or prove that visits caused higher grades.
