Is The standard deviation of all possible sample proportions increases as the sample size increases?

The standard deviation would generally decrease because the large the sample size is, the more we know about the population, so we can be more exact in our measurements.

Is it possible that the standard deviation is less than one?
Yes, a standard deviation can be less than one.
What happens to the standard score as the standard deviation increases?
The absolute value of the standard score becomes smaller.
When the size of a representative sample increases does the mean range median or standard deviation decrease?
mean
The precision with which a sample average approximates a population average increases as?
the standard deviation of the sample decreases.
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
What happens to the confidence interval as the standard deviation of a distribution increases?
The standard deviation is used in the numerator of the margin of error calculation. As the standard deviation increases, the margin of error increases; therefore the confidence interval width increases. So, the confidence interval gets wider.
How are the mean and standard deviation affected by an outlier?
The mean is "pushed" in the direction of the outlier. The standard deviation increases.
As the sample size increases the standard deviation of the sampling distribution increases?
No.
Is it possible that the standard deviation is less than one?
Yes, a standard deviation can be less than one.
What happens to the standard score as the standard deviation increases?
The absolute value of the standard score becomes smaller.
Does the distribution of sample means have a standard deviation that increases with the sample size?
No, it is not.
Is it possible for a standard deviation to be negative?
no it is not possible because you have to take the square of error that is (x-X)2. the square of any number is always positive----------Improved answer:It is not possible to have a negative standard deviation because:SD (standard deviation) is equal to the square of V (variance).
Is it possible for the mean and standard deviation to be equal?
Yes.
Is it possible that in standard normal distribution standard deviation known and mean unknown?
it is possible to distribute standard deviation and mean but you dont have to understand how the mouse runs up the clock hicorky dickory dock.
What are the four numbers have the smallest possible standard deviation?
If all four numbers are the same, there is no standard deviation. The mean will be equal to all 4 numbers, resulting in a 0 standard deviation. Ex) 5,5,5,5
The precision with which a sample average approximates a population average increases as?
the standard deviation of the sample decreases.
When the size of a representative sample increases does the mean range median or standard deviation decrease?
mean
