Calculated values from a sample are referred to as statistics. These values, such as the sample mean, median, mode, variance, and standard deviation, summarize and describe characteristics of the sample data. They are used to make inferences about the broader population from which the sample is drawn.

What is a sample statistics?
It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.
Is the sample mean equal to one of the values in the sample?
The sample mean is not necessarily equal to one of the values in the sample. It is calculated by summing all the values in the sample and dividing by the number of observations. While the mean can coincide with one of the sample values, this is not a requirement and often does not occur, especially in larger or more diverse data sets.
What is the set of input values called?
In a statistical context this is usually called a sample.
Is the standard deviation of the data values in a sample is 17 what is the variance of the data values?
The variance of a set of data values is the square of the standard deviation. If the standard deviation is 17, the variance can be calculated as (17^2), which equals 289. Therefore, the variance of the data values in the sample is 289.
Are the sample mean and sample proportion of a population are called population parameters?
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.

What is the formula for calculating the mean of a sample, represented by the symbol "" in statistics?
The formula for calculating the mean of a sample, represented by the symbol "" in statistics, is to add up all the values in the sample and then divide by the total number of values in the sample. This can be written as: x / n, where x represents the sum of all values in the sample and n is the total number of values in the sample.

WHAT DOES X BAR MEANS IN STATISTICS?
In statistics, "x-bar" (denoted as (\bar{x})) represents the sample mean, which is the average of a set of values in a sample. It is calculated by summing all the observations in the sample and dividing by the number of observations. The sample mean is used to estimate the population mean and is a key concept in inferential statistics.
If the variance of the data values in a sample is 169 what is the standard deviation of the data values?
For a sample, the SD is 13.53, approx.
What is the single quantity compared to an entire sample?
The single quantity compared to an entire sample is called a statistic. It is a numerical measurement calculated from the data in the sample, such as the mean, median, or standard deviation. The statistic provides insight into the characteristics or properties of the sample as a whole.
