It means that the probability density function is symmetric about 0.
The mean of a distribution of scores is the average.
The mean of a distribution gives no information about the standard deviation.
The total deviation from the mean for ANY distribution is always zero.
The normal distribution.
le standard normal distribution is a normal distribution who has mean 0 and variance 1
An even distribution of sunlight.
The mean of a distribution of scores is the average.
The mean of the sampling distribution is the population mean.
The distribution of the sample mean is bell-shaped or is a normal distribution.
The exponential distribution and the Poisson distribution.
The mean of a distribution gives no information about the standard deviation.
The mean of a standard normal distribution is 0.
In a normal distribution half (50%) of the distribution falls below (to the left of) the mean.
The total deviation from the mean for ANY distribution is always zero.
Mean means Average of a particular distribution Mean means Average of a particular distribution
The answer will depend on the distribution of the weights. There is no basis for assuming that the distribution is normal, or even symmetrical.
The normal distribution.
