Activity 2. Incomplete Directions: Read and analyze the given situations. Write your answers on a separate sheet. A. Carmen kept a tally of the number of calls she received each day for a week. Plot the missing point by using the data in the table and connect the points to complete the line graph below. Calls Carmen received Day | Calls Monday | 3 Tuesday | 0 Wednesday | 6 Thursday | 7 Friday | 10 B. A junior high school student counted the number of bricks in each fence in his neighborhood. Draw the missing bar by using the data in the table to complete the histogram below. Bricks per fence Number of bricks | Number of fences 0-19 | 3 20-39 | 2 40-59 | 4 60-79 | 1 80-99 | 3 C. The owner of an orchard measures the height of every tree in centimeters (cm). Plot the missing point by using the data in the table and connect the points to complete the ogive below. Height of the tree (cm) | Frequency | Cumulative Frequency | Cumulative Percentage 1-50 | 5 | 5 | 5% 51-100 | 30 | 35 | 32% 101-150 | 25 | 60 | 55% 151-200 | 50 | 110 | 100%

1 For the accompanying data set, (a) draw a scatter diagram of the data, (b) by hand, compute the correlation coefficient, and (c) determine whether there is a linear relation between x and y. (a) Draw a scatter diagram of the data. Choose the correct graph below. A. A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 18); (4, 7); (7, 12); (7, 8); (8, 4). B. A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 2. The following 5 points are plotted, listed here from left to right: (2, 4); (4, 8); (7, 12); (7, 12); (8, 18). C. A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 2. The following 5 points are plotted, listed here from left to right: (2, 18); (4, 12); (7, 12); (7, 8); (8, 4). D. A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 4); (4, 8); (7, 12); (7, 7); (8, 18). (b) By hand, compute the correlation coefficient. The correlation coefficient is r = (Round to three decimal places as needed.) (c) Determine whether there is a linear relation between x and y. Because the correlation coefficient is [positive/negative] and the absolute value of the correlation coefficient, [value], is [greater/not greater] than the critical value for this data set, [value], [a negative/no/a positive] linear relation exists between x and y. (Round to three decimal places as needed.)

The purpose of this article is to examine how technology has impacted computer graphics and data presentation. It is important to note that not all data can be represented accurately with a straight line. In some cases, a scatter plot may be more appropriate. Additionally, different colors and shapes can be used to represent different data sets. It is also important to consider the slope and intercept of the trend line when analyzing the relationship between variables. Overall, graphs should be clear and concise, and should accurately represent the data being presented.
