To describe a distribution's shape — where the data clumps, where the peak is, whether it leans left or right — you must first read a number line and a bar/dot plot, find the tallest bar, and compare counts. Warm those feeders and shape talk makes sense.
These are words you'll need to already know to follow this lesson — not the new words the lesson teaches. Review each one, its meaning, and the example so the new lesson makes sense from the start.
Level 1 A line where numbers are placed in order from small to big.
Example: On a number line, 7 is farther right than 2.
Level 1 A graph that stacks a dot for each value above a number line.
Example: Three dots above the value 5 mean 3 people chose 5 on the dot plot.
Level 1 The biggest amount or count out of all of them.
Example: Counts 1, 4, 2: the value with 4 has the most.
Level 1 To look at amounts and see which is bigger or smaller.
Example: Compare a bar of 6 and a bar of 3: 6 is more.
These check the skills you'll need for this lesson — not the new lesson itself. Answer all 3, then press Show my path. No grade — it just suggests where to start.
1. On a number line, which value is farthest to the right: 2, 7, 4?
2. Counts at each value are 1, 4, 2. Which value has the most (the peak)?
3. Which is more, a bar of 6 or a bar of 3?
