There is a set of 100 observations with a mean of 50 and a standard deviation of 0 What is the value of the smallest observation in the set?
If there is zero deviation all the observations are 50.
The mean and standard deviation of a population being sampled are 64 and 6 respectively. If the sample size is 50 what is the standard error of the mean?
0.75
What does standard deviation tell about distribution and varity?
It is a measure of the spread of the distribution. The greater the standard deviation the more variety there is in the observations.
For a set of 100 observations with a mean of 46 and a standard deviation of 0 What is the value of the smallest observation in the set?
There is no actual "smallest" observation - a standard deviation of zero means that all 100 of the observations had to be 46.
In the Empirical Rule of data will fall in with two standard deviation.?
Approx 95% of the observations.
A normal curve is determined by which two population parameters?
1. mu (population mean) 2. sigma (population standard deviation)
There is a set of 100 observations with a mean of 50 and a standard deviation of 0 What is the value of the smallest observation in the set?
If there is zero deviation all the observations are 50.
The mode and standard deviation of a distribution are 55 and 4.33 respectively?
The statement is probably: The mean and standard deviation of a distribution are 55 and 4.33 respectively.
The mean and standard deviation of a population being sampled are 64 and 6 respectively. If the sample size is 50 what is the standard error of the mean?
0.75
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
How can he return and standard deviation of a portfolio be determined?
How can the return and standard deviation of a portfolio be deteremined
What does standard deviation tell about distribution and varity?
It is a measure of the spread of the distribution. The greater the standard deviation the more variety there is in the observations.
For a set of 100 observations with a mean of 46 and a standard deviation of 0 What is the value of the smallest observation in the set?
There is no actual "smallest" observation - a standard deviation of zero means that all 100 of the observations had to be 46.
What is the standard deviation?
The standard deviation of a set of data is a measure of the spread of the observations. It is the square root of the mean squared deviations from the mean of the data.
What is the standard deviation of 157 160 161 172 165 149?
The standard deviation if the data is a sample from a population is 7.7115; if it is the population the standard deviation is 7.0396.
What is mean and standard deviation?
They are statistical measures. For a set of observations of some random variable the mean is a measure of central tendency: a kind of measure which tells you around what value the observations are. The standard deviation is a measure of the spread around the mean.
Is population standard deviation the same thing as absolute standard deviation?
No.
