Domain - Statistics and Probability

Cluster - Investigate chance processes and develop, use, and evaluate probability models.

[7.SP.C.7] - Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.

Resources:


  • Probability
    A number between 0 and 1 used to quantify likelihood for processes that have uncertain outcomes (such as tossing a coin, selecting a person at random from a group of people, tossing a ball at a target, testing for a medical condition).
  • Probability model
    A probability model is used to assign probabilities to outcomes of a chance process by examining the nature of the process. The set of all outcomes is called the sample space, and their probabilities sum to 1.

Successor Standards:

  • AII.S-IC.A.2
    Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation. For example, a model says a spinning coin falls heads up with probability 0.5. Would a result of five tails in a row cause you to question the model?
  • MIII.S-IC.A.2
    Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation.* For example, a model says a spinning coin falls heads up with probability 0.5. Would a result of five tails in a row cause you to question the model?

Same Level Standards:

  • 7.RP.A.3
    Use proportional relationships to solve multi-step ratio, rate, and percent problems. For example: simple interest, tax, price increases and discounts, gratuities and commissions, fees, percent increase and decrease, percent error.
  • 7.SP.C.6
    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.
  • 7.SP.C.8
    Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation.
