1. The mean applies to the whole dataset while this statistic applies to each value in the dataset and is used to compute the variance and standard deviation of the dataset. Name the statistic I am talking about here.
2. What do the Normal Model and the Linear Model have in common?
3. How does the Normal Model differ from the linear, quadratic, exponential, sinusoidal and logarithmic models?
4. If you know that a dataset is normally distributed, describe a way in which you can provide a rough estimate of the range of the dataset.
