Tables, Graphs & Patterns in Data — Drills · Grade 6 Science
Chapter: Inquiry, Measurement & ModelsWhat these drills covers
By the end of Tables, Graphs & Patterns in Data you should be able to:
- I can build a results table with units in the headings and a column for the mean.
- I can choose between a bar chart and a line graph from the kind of data I have.
- I can tell the difference between reading inside my data and guessing beyond it.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: mean, pattern, evidence, system boundary, uncertainty.
Problem 1
- A sample with missing measurements has proved those values are zero.
- A missing value is automatically a measured zero.
- A graph’s association automatically establishes a cause.
- mean: The sum of comparable values divided by their count.
Answer and explanation
mean: The sum of comparable values divided by their count.
The sum of comparable values divided by their count.
Problem 2
- pattern: A relationship observed in records that may guide a test or explanation.
- A graph’s association automatically establishes a cause.
- A missing value is automatically a measured zero.
- Repeating any method makes every causal claim true.
Answer and explanation
pattern: A relationship observed in records that may guide a test or explanation.
A relationship observed in records that may guide a test or explanation.
Problem 3
Answer and explanation
No. It summarizes three values; the individual loads differ and should remain available.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 4
Answer and explanation
No. Clear display improves interpretation but cannot remove a problem in how the evidence was collected.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
