Name: Continuous Random Variables: Continuous Distribution Lab Collect the Data: Use a random number generator to generate 50 values between 0 and 1 (inclusive). List them below. Round the numbers to 4 decimal places or set the calculator MODE to 4 places. Complete the table Calculate the following: 1t quartile Organize the Data Construct a histogram of the empirical data. 3rd quartile median Construct a histogram of the empirical data. Make 8 bars. Make 5 bars. Relative Frequency Relative Frequency Describe the Data: Describe the shape of each graph. Use 2-3 complete sentences. (Keep it simple. Does the graph go straight across, does it have a V shape, does it have a hump in the middle or at either end, etc.? One way to help you determine a shape, is to roughly draw a smooth curve through the top of the bars.) Describe how changing the number of bars might change the shape
Theoretical Distribution In words, X The theoretical distribution of X is XU(O, 1). In theory, based upon the distribution X~ U(O, 1), find 1t quartile _ 3rd quartile median- Are the empirical values (from "Collect the Data") close to the corresponding theoretical values in Theoretical Distribution above? Why or why not? Plot the Data Construct a box plot of the data. Be sure to use a ruler to scale accurately and draw straight edges Do you notice any potential outliers? If so, which values are they? Either way, numerically justify your answer. (Recall that any DATA are less than Q1-1.5%QR or more than Q3 15"OR are potential outliers. QR means interquartile range.) Compare the Data For each part below, use a complete sentence to comment on how the value obtained from the data compares to the theoretical value you expected from the distribution X~ UIO, 1) minimum value: third quartile 1t quartile maximum value: median: width of IQR: overall shape: Based on your above comments, how does the box plot fit or not fit what you would expect of the distribution X~ 내0,1)? Discussion Question: Suppose that the number of values generated was 500, not 50. How would that affect what you would expect the empirical data to be and the shape of its graph to look like?

    Unit 6 Lesson 3 Classwork (Adapted from Math Vision Project) Data Distribution A lot of information can be obtained from looking at data plots and their distributions. It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others). Skewed distribution: when most data is...
