Yes, the voltages appear to follow a normal distribution; the values are not concentrated near the
ends of the distribution.
No, the voltages do not appear to follow a normal distribution; instead of being concentrated near the
middle of the distribution, the values appear to be rather evenly distributed.
No, the voltages do not appear to follow a normal distribution; instead of being concentrated near the
ends of the distribution, the values appear to be rather evenly distributed.
Yes, the voltages appear to follow a normal distribution; the values appear to be rather evenly
distributed.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
