For the following line graph, State at least one type of conclusion that could be made from the data provided for the KPI. Suggest one other data source that would provide more information to make data-driven decisions. Explain what information that source would supply. (I used the clustered bar chart) Examples: 1) The completion KPI measures the percentage of South Texas College students who finished their degree or certificate program within six years. From the line graph, it can be seen that the completion rates have remained nearly constant through the years. Data from the THECB was used in this case. 2) Information about the percentage of students who receive credit for attempted courses is available on the South Texas College KPI webpage. According to the data, over the past five years, an increasing number of students have been receiving credit for courses they have attempted. Data on the percentage of students who complete courses, the percentage of students who withdraw…

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.
Consider the women's 100-yd dash (and the subsequent 100-m dash) in the Olympics since records have been kept. Determine the best way to combine all data and depict the data. Choose the correct answer below. O A. A line graph would be the best way to show all of the data over time, but some measurements would have to be converted to display the 100-yd and 100-m on the same graph. OB. A scatterplot would show the relationship between the 100-yd dash and the 100-m dash. O C. A stem and leaf plot would be the best way to show all of the data grouped by race times. O D. A histogram would show all of the data by comparing each year. The units of distance would not matter.

Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. Yi=2+8Xi a. Interpret the meaning of the Y-intercept, b0. Choose the correct answer below. A. The Y-intercept, b0=8, implies that when the value of X is 0, the mean value of Y is 8. B. The Y-intercept, b0=2, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 2 units. C. The Y-intercept, b0=2, implies that the average value of Y is 2. D. The Y-intercept, b0=2, implies that when the value of X is 0, the mean value of Y is 2. b. Interpret the meaning of the slope, b1. Choose the correct answer below. A. The slope, b1=8, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 8 units. B.
