Create the graphs: Follow the instructions in Unit 2 Discussion video: Graphical Displays to generate your three random sample datasets and copy and paste special

Create the graphs: Follow the instructions in Unit 2 Discussion video: "Graphical Displays" to generate your three random sample datasets and copy and paste special to a new Excel workbook that you will save to your computer. In the new workbook, you will follow the video instructions to generate an appropriate graphical display for all three samples. Then you can use the snipping tool to copy and paste your graphs directly into the body of your discussion post.
Describe the graphs:
1. Shape: Describe the shape of the graph (skewness or symmetry) for each group and anything unusual that you see.
2. Center: From the graphs, estimate the center of each group (median and mean) and order the three groups from smallest to largest center. Do you think the mean and median are similar in each group, or is there some group where you think the mean and median will differ? Explain your reasoning.
3. Spread: From the graphs, estimate the spread of each group (range=max-min or IQR=Q3-Q1) and order the three groups from smallest to largest spread.
Create numerical summaries: Follow the instructions in Unit 2 Discussion video: "Numerical Summaries" to generate descriptive statistics for each of the three groups. Then you can use the snipping tool to copy and paste your statistics directly into the body of your discussion post.
Describe the numerical summaries:
1. Center: Compare and contrast the central tendency (medians and means) of the three groups. Put them in order from smallest to largest center. Is this order what you expected based on your estimates in part B? If it differs, describe the differences.
2. Spread: Compare and contrast the spread (range=max-min and standard deviation) of the three groups. Put them in order from smallest to largest spread. Is this order what you expected based on your estimates in part B? If it differs, describe the differences.
Inference: Based on what you said in parts B and D, do all three of your sample groups seem like they could have come from the same population? Do any of the groups seem like they could have come from a different population? Explain your response using the statistics and graphs you generated. Make sure to attach your .XLS file to your post.
