What's one and a half questions you have about standard deviation?
What's one-and-five-sixths questions you have about the normal curve?
Draw a normal curve. Then draw in the standard deviation lines. Then, write in the percentage of the sample that lies between each standard deviation line.
Draw two normal curves. Draw the first curve in red that has a large mean. Draw the second curve in blue with a relatively smaller mean.
Draw two normal curves. Draw the first curve in red that has a large standard deviation. Draw the second curve in blue with a relatively smaller standard deviation.
Now, draw a positively skewed normal curve. Then draw vertical lines where the mode, median, and means would lie orange, yellow, and green, respectively.
Now, draw a negativetly skewed normal curve. Then draw vertical lines where the mode, median, and means would lie orange, yellow, and green, repes
