14 Instructional Days - 5th 6 Weeks
Hyperlinks are for content teachers
Big Idea:
Analyze data in order to make inferences about a population.
Student Expectations:
Priority TEKS
7.6(G) [Readiness] Solve problems using data represented in bar graphs, dot plots, and circle graphs, including part-to-whole and part-to-part comparisons and equivalents.
7.12(A) [Readiness] Compare two groups of numeric data using comparative dot plots or box plots by comparing their shapes, centers, and spreads.
Focus TEKS
7.12(B) [Supporting] use data from a random sample to make inferences about a population
7.12(C) [Supporting] compare two populations based on data in random samples from these populations, including informal comparative inferences about differences between the two populations.
Ongoing TEKS
7.3(A) [Supporting] Add, subtract, multiply, and divide rational numbers fluently.
Student Learning Targets:
- I will compare populations using bar graphs, dot plots, circle graphs, and box-whisker plots.
- I will make predictions about a population.
- I will determine the difference between biased and unbiased samples.
- I will select an appropriate display.
Essential Questions:
- How do we know which type of graph to use when displaying data?
- How can statistics help us make inferences about a population?
