A student collected data about the heights and weights of ten classmates, hoping to develop a model that would use a teenager's height to estimate his weight. Here are the summary statistics: Mean St. Dev. Correlation Height 68 4 r=0.7 a. Find the slope of the LSRL. Weight 150 25

Construct a stem and leaf plot by using each leading digit twice. Does this technique improve the presentation of the data? Explain.

The dot plot shows the grades received on a recent test. : 十 70 75 80 85 90 95 100 Question 1: What is the range of the data? Question 2: What is the median of the data? the mode of the data? Question 3: What is Question 4: What is the mean of the data?

Objective: Students will be able to 1) Create a box-and-whisker plot, 2) Interpret a box-and-whisker plot, and Identify cumulative frequency. How do I interpret a box-and-whisker plot? I 1. What does the x-axis show? Boys 2. What does the y-axis represent? 3. What does the length of Girls each of the lines (red and green) mean? 4. Does the size of the box 2. 8 10 12 14 16 18 20 22 24 Time (s) matter? How to create a box-and-whisker plot: To draw a box-and-whisker plot you need five pieces of information, called the five-number summary: the smallest value, the lower quartile (LQ), the median, the upper quartile (U0) and the largest value. An outlier is a value that is much smaller or much larger than the other values. An outlier is a point less than the LQ-1.5x 1QR or greater than the UQ+1.5xIQR.
