What is sample?
A sample is a subcollection of members selected from a population. (Ref Triola, Elementary Statistics). A sample may be real or hypothetical. Real- Ten patients at the hospital were interviewed about the care they received. Hypothetical- Repeatedly drawing n independent, and identical values X1, X2... Xn from a normal distribution to form a random sample, the mean of this sample should conform to a normal distribution, if the sample size is greater than 30.
What are the classification of variables according to continuity of values in statistics?
what are the classification of variables
In statistics what does the empirical rule states?
Nearly all the values in a sample from a normal population will lie within three standard deviations of the mean. Please see the link.
What are the importance of the mean in statistics?
the mean is important in statistics because you will find out your average and can compare that mean to other things..
What is the difference between statistics and parameters?
Parameter is any attribute Statistic are the measured values of a parameter. A statistic is a sample value such as the average height of a group of students. A parameter is a functional constant such as the mean of a normal distribution. Statistics are often used to estimate parameters. For instance, a sample average is an estimate of the mean.
What does sy mean in mathematics?
In statistics it could mean the sum of the values for the y-variable.
How do you put the mean on a document using openoffice?
In statistics, mean has three related meanings:the arithmetic mean of a sample (distinguished from the geometric mean or harmonic mean).the expected value of a random variable.the mean of a probability distribution.Which do you "mean"?the arithmetic mean is just the sum of the values divided by the number of values.
When do you use mean and median?
The mean is used to measure the average of a set of values, especially when the data is normally distributed. The median is used to find the middle value of a dataset when there are extreme values or outliers present, as it is less affected by extreme values.

What is z-chart in statistics?
A z-chart in statistics is a chart that contains the values that represent the areas under the standard normal curve for the values between 0 and the relative Z-score.
Statistics may be regarded as the study of the reduction of the data?
The answer is generally no. I note there is no hard and fast definition of the field of statistics. The definition of the field or discipline of statistics is not to reduce the number of values in the set of collected data. An objective of statistics is to characterize or add meaning to the collected data, through calculated values of the data. In this sense, statistics summarizes the data.
What does it mean to generate random numbers in Java?
Generating random numbers in Java is somewhat of a misnomer because the numbers are actually semi-random.It means to use the program to obtain random integers to use in hypothetical situations such as statistics.
What are the classification of variables according to continuity of values in statistics?

What does Sx2 mean in statistics?
In statistics, this is the symbol for the "Variance"
Can average be regarded as best for all times all data?
No. The three averages are mean, mode and median. Mean is the total values divided by the number of values; mode is the number occurring most often; median is the middle value (or the value halfway in between the two middle values) when all values are in order. What you have described is basically the maximum (highest/best value) times the number of values, which has no major use in statistics.

Nearly all the values in a sample from a normal population will lie within three standard deviations of the mean. Please see the link.
What does mean mean in statistics?
Mean is the average.
