Not if the attribute recorded in qualitative rather than quantitative. If you ask a group of people what their favourite fruit is, a mean of their answers has no meaning.

What is a sample statistics?

What are Calculated values from a sample are called?

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 the symbol for sample mean?

The symbol for sample mean is typically represented by ( \bar{x} ) (pronounced "x-bar"). It is calculated by summing all the observations in a sample and dividing by the number of observations. This statistic provides an estimate of the population mean based on the sample data.


What does it mean to have a sample with a standard deviation of zero?

A sample with a standard deviation of zero indicates that all the values in that sample are identical; there is no variation among them. This means that every observation is the same, resulting in no spread or dispersion in the data. Consequently, the mean of the sample will equal the individual values, as there is no deviation from that mean.


What is the standard deviation of the sample means called?

The standard deviation of the sample means is called the standard error of the mean (SEM). It quantifies the variability of sample means around the population mean and is calculated by dividing the population standard deviation by the square root of the sample size. The SEM decreases as the sample size increases, reflecting improved estimates of the population mean with larger samples.

What is the difference between the population mean and sample mean?

The population mean is the mean calculated over every member of the set of subjects being studied. It is usually not available and a survey is used to find an estimate for the population mean. The mean value of the variable in question, calculated from only the subjects included in the sample (or survey) is the sample mean. Provided some basic statistical requirements are met, the sample mean is a "good" estimate of the population mean.


How does one calculate the standard error of the sample mean?

Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.

What does simple random sample mean in statistics?

It means that every member of the population has the same probability of being included in the sample.


What does randomisation mean?

It means that the every element in a population has an equal chance of being selected to be in the sample which is studied. Equivalently, in considering a sample of a particular size, every possible sample of that size has the same chance of being selected.

What does the term coefficient of variation mean?

The Coefficient of Variation is a ratio showing the degree to which individual points of data in a sample deviate from the mean. It is calculated by taking the standard deviation of the sample and dividing that by the mean of the sample. It can be useful for comparing different data sets because it is a ratio (or percentage) and not an absolute number.


A numerical value calculated for a sample is called a?

A numerical value calculated for a sample is called a descriptive statistic.


The closer the sample mean is to the population mean?

Your question is a bit difficult to understand. I will rephrase: In hypothesis testing, when the sample mean is close to the assumed mean of the population (null hypotheses), what does that tell you? Answer: For a given sample size n and an alpha value, the closer the calculated mean is to the assumed mean of the population, the higher chance that null hypothesis will not be rejected in favor of the alternative hypothesis.


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.


What does the word statistic mean?

A statistic is a value calculated from a data sample. For example, the mean (average) is a statistic. You calculate the mean by adding up the values of the data you have and dividing by the number of values. Usually, you want to know the corresponding value for the whole population but this is impossible to obtain in practice. So you have to use a statistic calculated from a sample. For eaxmple, if you want to know the height of sixteen year old students in the UK, you cannot measure every single student. So you measure a sample (selected randomly), and calculate the average height of the sample. This is a statistic. See: http://www.stats.gla.ac.uk/steps/glossary/basic_definitions.html#stat
