What is the formula of finding mean using direct method?
formula for finding mean through direct mean method: sigma fi xi /sigma fi
Z-score responding to 10 hours?
The z-score can't be calculated with the information given. A mean & standard deviation is required to put into the formula: Z = (x-mean)/sigma. Your x value is 10.
What is the z value of a mean of 516 hours and a standard deviation of 20 hours?
The Z Value, or Z Score, does not apply to the mean, it is a representation of a piece of data. z = (x-µ)/sigma
If your mean is 33.7 and your standard deviation is 33.7 what is your z score?
Z-score is the x value minus the mean, all divided by the standard deviation; or z=(x-mu)/sigma. The "x" value needs to be given to answer the question.
What does formula mean in maths?
A formula is math sentence where you substitute numbers for letters and solve to get an unknown value.

What does the greek capital sigma symbol mean in statistics?
It means the sum total.
Coefficient of Deviation?
Coefficient of deviation (CV) is a term used in statistics. It is defined as the ratio of the standard deviation (sigma) to the mean (mu). The formula for CV is CV=sigma/mu.
When determining the 95 percent confidence interval for a population mean with known sigma the value of the critical value of z is equal to?
1.96
Use the computational formula to find the standard deviation of the following set of data 5 7 17 31 45 47 68 85 96 99?
33.79 I used the formula SD = sq rt {Sigma[(x - mean)^2]/n} where sigma means the sum of; ^2 means squared. Firstly, find the mean of the data = 50. Subtract each term separately from the mean and square it. Add these 10 terms and it comes to 11424 Divide by the number of terms, 10 = 1142.4 Then find the sq rt = 33.79.
How do I find the Z score for tests with mean of 100 and a standard deviation of 20?
Z = (x-mu)/sigma. So, for your example, any x value can be transformed to Z-score by the formula Z = (x-100)/20.
What is the z value of a mean of 516 hours and a standard deviation of 20 hours?
The Z Value, or Z Score, does not apply to the mean, it is a representation of a piece of data. z = (x-µ)/sigma
What does BAKED - the Gamma Sigma secret motto - mean?
It means keep your mouth shut! It means All Eternal Kings Drink Budwieser!
What is the formula of finding the mean of grouped data using coded formula?
Mean = Xam + (∑fd over N) i Where i: (Upper Value - Lower Value) / no. of classes
