Connecting the Dots… — Class 7 Mathematics

This chapter introduces statistical thinking — making sense of the world through data. A statistical statement is a claim summarising a phenomenon in numbers, proportions, probabilities or predictions ("David spends about 7 hours daily in school"), while a statistical question is one that needs data to answer ("How tall are Grade 7 students in our school?"), because we expect the answers to vary. You learn to collect data, organise it, and represent it visually so patterns become clear. The chapter develops ways to summarise and compare data sets and to read graphs and tables critically, distinguishing what the data actually shows from what it does not. A key idea is variability — not everyone is the same height or takes the same time — and how a single summary value or a chart can communicate the overall picture. By connecting scattered data points into a meaningful story, you begin to reason about typical values, trends and predictions, while staying alert to misleading or incomplete claims.
