DSP Data Analysis, Statistics and Probability

  • DSP.A Use random sampling to draw inferences about a population.

    • DSP.A.1 Understand that statistics can be used to gain information about a population by examining a sample of the population.

      • DSP.A.1.a Understand that a sample is a subset of a population.

      • DSP.A.1.b Understand that generalizations from a sample are valid only if the sample is representative of the population.

      • DSP.A.1.c Understand that random sampling is used to produce representative samples and support valid inferences.

    • DSP.A.2 Use data from multiple samples to draw inferences about a population and investigate variability in estimates of the characteristic of interest.

  • DSP.B Draw informal comparative inferences about two populations.

  • DSP.C Develop, use and evaluate probability models.

    • DSP.C.1 Investigate the probability of chance events.

      • DSP.C.1.a Determine probabilities of simple events.

      • DSP.C.1.b Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring.

    • DSP.C.2 Investigate the relationship between theoretical and experimental probabilities for simple events.

      • DSP.C.2.a Predict outcomes using theoretical probability.

      • DSP.C.2.b Perform experiments that model theoretical probability.

    • DSP.C.3 Explain possible discrepancies between a developed probability model and observed frequencies.

      • DSP.C.3.a Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events.

      • DSP.C.3.b Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process.

    • DSP.C.4 Find probabilities of compound events using organized lists, tables, tree diagrams and simulations.

      • DSP.C.4.a Represent the sample space of a compound event.

      • DSP.C.4.b Design and use a simulation to generate frequencies for compound events.
