I have a regression project where I have to pick a real life situation data and answer questions.
here is my data:

18 data points were entered:
4.00 4.20 4.50 4.60 4.60 4.70 4.90 5.10 5.40 5.50 5.60 5.60 5.80 6.00 6.10 6.80 6.90 7.50

Mean = 5.43

95% confidence interval for actual Mean: 4.951 thru 5.916

Standard Deviation = 0.971

Hi = 7.50 Low = 4.00

Median = 5.45

Average Absolute Deviation from Median = 0.767

SO One of my questions require me to make a Bell Curve. According to my data I can't.. because I have two medians. I read online that when you have two medians it forms a Bimodal curve. I am so confused because in math B2 they only teach you about the Normal curve. Please help!

You have only one median, 5.45.

Is the data from a 'discrete variable' or a 'continuous variable'?
