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.

MAT-07.SP.03

7th Grade MAT Targeted Standards
Domain (SP) Statistics and Probability
Cluster: TOPIC

MAT-07.SP.03 Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.

For example, the mean height of players on the basketball team is 10 cm greater than the mean height of players on the soccer team, about twice the variability (mean absolute deviation) on either team; on a dot plot, the separation between the two distributions of heights is noticeable.

Student Learning Targets:

  • I can find the difference in the mean or the median of two different data sets.
  • I can demonstrate how two data sets that are very different can have similar variabilities. 
  • I can draw inferences about the data sets by making a comparison of these differences relative to the mean absolute deviation or interquartile range of a set of data. 

Vocabulary:

Measures of Center (Measures of central tendencies)

Variability

mean

median

mode

mean absolute deviation

interquartile range.

MAT-07.SP.04

7th Grade MAT Targeted Standards
Domain (SP) Statistics and Probability
Cluster: Draw informal comparative inferences about two populations

MAT-07.SP.04 Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.

For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book.

Student Learning Targets:

  • I can apply central measures t draw conclusions.
  • I  draw conclusions from different population samples.
  • I can make inferences about two populations.

MAT-07.SP.05

7th Grade MAT Targeted Standards
Domain (SP) Statistics and Probability
Cluster: Investigate chance processes and develop, use, and evaluate probability models

MAT-07.SP.05 Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around ½ indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.

Student Learning Targets:

  • I can define probabilite as a ratio that compares favorable outcomes to all possible outcomes.
  • I can recognize and explain that probabilities are expressed as a number between 0 to 1.
  • I can interpret a probability near 0 as unlikely to occur and a probability near 1 as likely to occur.
  • I can interpret a probability near 1/2, as being equally able to occur as to not occur

 

Vocabulary:

Likely

unlikely

MAT-07.SP.06

7th Grade MAT Targeted Standards
Domain (SP) Statistics and Probability
Cluster: Investigate chance processes and develop, use, and evaluate probability models

MAT-07.SP.06 Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability.

For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times.

Student Learning Targets:

  • I can collect data on a chance process to approximate its probability.
  • I can use probability to predict the number of times a particular event will occur given a specific number of trials.
  • I can use variability to explain why the experimental probability will not always exactly equal the theoretical probability.

Vocabulary

Theoretical Probability

Experimental Probability

Relative Frequency

  • b. Develop a possibly model (which may not be uniform) by observing frequencies in data generated from a chance process.
