Question 1 of 10
The notion that taking random samples from the population would generate different means is called...
sample variation
sample constancy
sampling distribution
sample distribution
Question 2 of 10
The definition of a sample distribution is...
the distribution of sample values
the distribution of sample means
the distribution of sample proportions
the distribution of scores in a sample
Question 3 of 10
The sampling distribution is often referred to as...
Question 4 of 10
To generate a sample distribution, you need...
one sample with at least 1 value
one sample with at least 2 values
multiple samples with at least 1 value each
multiple samples with at least 2 values each
Question 5 of 10
To generate a sampling distribution, you need...
Question 6 of 10
According to the central limit theorem, the sampling distribution of sample means forms a normal distribution when...
the sample size of your sample distributions is 30 or greater
the number of samples in your sampling distribution is 30
there are 30 sample means from a population
the sample size is 30 and there are 30 sample means
Question 7 of 10
According to the central limit theorem...
the mean of all possible sample means equals the population mean
the sample mean is an approximation of the population mean
there is no way to know the true population mean
30 sample means will equal the population mean
Question 8 of 10
the standard deviation is equal to the population standard deviation
the standard deviation divided by sqrt(N) equals the standard error of the mean
the sampling distribution of the standard deviations equals the population standard deviation
the standard deviation equals the standard error of the mean
Question 9 of 10
The standard error of the mean is equivalent to...
the standard deviation of the sampling distribution
the standard deviation divided by the sqrt(N)
the standard deviation
Options 1 and 2
Question 10 of 10

uniform distributions
skewed distributions
bimodal distributions
none of the above
