For example, If a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction ½ / ¼ miles per hour, equivalently 2 miles per hour.

(SP) STATISTICS AND PROBABILITY

MAT-07.SP

BPSS-MAT logoDomain (SP)

Statistics and Probability

 Narrative for the (SP) Statistics and Probability

The standards within the Statistics and Probability domain require students to (1) use random sampling to draw inferences about a population, (2) draw informal comparative inferences about two populations, and (3) investigate chance processes and develop, use, and evaluate probability models.

Calculation Method for Domains

Domains are larger groups of related standards. The Domain Grade is a calculation of all the related standards. Click on the standard name below each Domain to access the learning targets and rubrics/ proficiency scales for individual standards within the domain.

MAT-07.SP.01

7th Grade MAT Targeted Standards
Domain (SP) Statistics and Probability
Cluster: Use random sampling to draw inferences about a population

MAT-07.SP.01 Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.

Student Learning Targets:

  • I can explain that inferences about a population can be made by examining a sample.
  • I can explain why the validity of a sample depends on whether the sample is representative of the population.
  • I can explain that random sampling tends to produce representative samples. 

Vocabulary:

Sample, Population, Validity, Generalization, Random Sample, and Representative Sample.

MAT-07.SP.02

7th Grade MAT Targeted Standards
Domain (SP) Statistics and Probability
Cluster: Use random sampling to draw inferences about a population

MAT-07.SP.02 Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions.

For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data. Gauge how far off the estimate or prediction might be.

Student Learning Targets:

  • I can draw inferences about a population based on data generated by a random sample.
  • I can generate multiple samples from the same population and analyze the estimates or predictions based on the variation of each sample.

Vocabulary:

Population, Sample, and Random Sample.
