# The Nature of the Data

Learning Goal: I’m working on a applied mathematics question and need support to help me learn.

• Describe the nature of the data. What do the data represent? Why did you choose this data set? How many data points are included?
• Describe the types of variables, the type of sample, possible lurking variables, and any association or causation.
• Create a histogram, describe the shape of the distribution, and find the mean and median.
• Compute the standard deviation, the five number summary, and the range and interquartile range. Provide a visual representation of this information.
• Find possible outliers (there may be none, but you will need to show how you determined that), draw a boxplot, create a scatterplot, and compute the sample correlation r.
• If you found a moderate to strong linear relation between the variables, compute the regression equation and describe how you could use a regression line to make predictions.
• Conclude with a summary of the major findings. How have these findings informed the topic, and what are the implications of the findings?
