Question

Which of the following is a potential problem when assesing the fit of the human brain to the glia-neuron ratio versus ln(brain mass) trend observed in other species.

1. The brain masses are not normally distributed.

2. ln(brain mass) is not normally distributed.

3. We are performing extrapolation.

4. The co-efficient of determination (R²) is too low.

Is the answer 1, 2, 3, or 4?

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.
