Solution

Solution Steps

To create a distribution that is nearly normal, the two key pieces of information needed are the mean and the standard deviation. The mean provides the central location of the distribution, while the standard deviation measures the spread or dispersion of the data around the mean.

Step 1: Define the Mean and Standard Deviation

To create a nearly normal distribution, we need the mean ($\mu$) and the standard deviation ($\sigma$). In this case, we have: \[ \mu = 0 \] \[ \sigma = 1 \]

Step 2: Generate the Normal Distribution

Using the mean and standard deviation, we generate a normal distribution. The data points are drawn from a normal distribution with the specified mean and standard deviation.

Step 3: Visualize the Distribution

We can visualize the distribution by plotting a histogram of the data points. The histogram will show the frequency of data points within specified bins, and we can overlay a line at the mean to indicate the central location of the distribution.

Final Answer

$\boxed{\text{Mean and Standard Deviation}}$
