Creating Graphs

Answer = The first part of the graph resembles a bell shape. At the latter part of the graph it takes a sharp increase.

Denote by the average heights for males and females, respectively. Here are the two hypotheses:

Present all relevant data in a data table below. Include an observations section for any observations you made during the lab. Make sure you note the data needs to be converted before graphing.

Part 1 – Complete the following chart using information from the lesson. Print the chart.

(a) Then mean of the sample and the value of Z with an area of 10% in right tail.

10. Identify whether these distributions are negatively skewed, positively skewed, or not skewed at all, and why.

I would use a bar graph because it would be easy to follow and understand the information presented.

7. Question : In a frequency distribution such as a bell-shaped curve, what does the vertical height of the curve indicate?

The performance had to be forced in a bell curve like curve where high performers could be maximum of 14%; Achievers (A) min 70%; Low Achievers (L) min 7% and Unacceptable (U).

Using a measuring tape on the wall each member of the lab group separately stood with either side against the tape and extended the arm beside the wall as high as possible. This height was recorded in centimeters. Next each lab member separately applied chalk to their fingertips, crouched down beside the tape on the wall, and jumped as high as they could while hitting the measuring tape at their highest point. This measurement was again recorded in centimeters. Then the height the lab member’s arm extended while standing was subtracted from the height when they jumped. This number denoted the vertical height jumped. For the jump height measurements a scatter plot was constructed. In order to do this, the data was again entered into excel, highlighted, insert chart and the first scatter plot choice was chosen. It was then that it was necessary to edit our axes and other parts of the graph. The x-axis was right-clicked and format axis was selected and fixed was selected and 20.0 was entered into the blank. Following this, a trend line was added to the graph by right clicking on a data point. A drop down popped up, and from there add trend line was selected from the choices.

Figure 3: The graph shows the differences between standard lengths of population A and B. It is easy to see the difference in size between the populations.

For the student height of girls, the data has a normal distribution because the data has a symmetrical spread around the mean. It has a bell shape.

Knowing this information, you need to first tell me, and then show this in your graph:

This survey spans across the mid-level and high-level schools of United States, which are believed to represent a cross-section of the national population. About 66 – 80% of the American schools participate in the survey on an average, and the students’ participation rate stands at an average of 79 – 83%.

Q7: Create a bar graph or pie chart of the data you have collected. For example, you could create a bar graph that shows the employee turnover rate in organizations that do offer flexible work arrangement compared to organizations that do not. Alternately, you could create a pie chart that shows which types of flexible work arrangement workers want the most.
