    Behaviors of the mean and median - CODAP
    This brief activity found on the CODAP site involves dragging points in a dot plot to explore the effect on the mean and median. The small data set includes 10 points and the large data set includes 100 points.

    Note: This activity introduced the learner to the sampler engine with hidden contents in the Mixer Device.
    The goal is to draw inferences about a population by looking at a random sample.

    Loading the Sampler - Tutorial
    This tutorial showcases how to move data from Data Cards to the Sampler. This allows the user to make inferences from a sample to a parent population.

    Learning Objective: In this lesson students will draw samples from a single population and explore the effect of sample size.
    Fish Length is a lesson developed by Key Curriculum. This lesson introduces the concept of making a claim about two populations based on random sampling.
    Vocabulary:
    The mean of the population is mu. The standard deviation of the population is the called sigma.
    The mean of the random sample is called x-bar. The standard deviation of the random sample is called s.

    The goal of the mammals slope activity is to develop the concept of slope by looking at the differences between the attributes height and sleep for 27 mammals. The horizontal and vertical ruler tool are used to calculate differences and a case table is used to compute rates of change.

    Cats - Slope and Residuals
    This TinkerPlots activity includes the analysis of a scatterplot of body length versus weight for 24 cats, estimating slope, use the y_hat equation to predict the body length for a given weight, use a residual value to predict the body length for a given weight, and indentify an influential point.

    MPG versus Car Weight
    This tutorial takes advantage of some of the statistical functions available in TinkerPlots. This is a bit more advanced in nature. The goal is to make connections between the given data, predicted values and residuals. The context is a set of 16 cars.
