Difference between calculating the sample mean and the population mean?
The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.
In basic statistics what is sample size and effective sample size?
sample size refers to the collection of data by only a selected size of te population through the process of sample surveys and sampling methods used in collecting data.
What is sample and population relationship?
The sample is a subset of the population. For example, the population may be all the people at your school. A sample might be 5 people from each class. There are different types of sampling methods. The most commonly used is a simple random sample. When your obtain data from the entire population this is called a census.
What type of statistics employ the use of sample data that is used to infer information about the population?
Inferential statistics.
A statistical function commonly used to describe a group of data?
A group of data is a sample.
How can you tell if the population data is related to the sample data?
There are Goodness-of-Fit tests that can be used. The choice of test will depend on what is known about the population and sample data.
What are the sources of data used in management accounting?
. Primary and Secondary data . Discrete and Continuous Data . Sample and Population Data
Why inferential statistics is not required in census?
Inferential statistical methods are used when data is collected from a sample in the population. Inferential statistics are used to generalize the results of the sample to the population. In a census you have data from each and every member of the population, so you just use descriptive statistics.

What term refers to the descriptors of variables computed from sample data used to estimate those same variables in the population?
Sample Statistics

What is a subset of measurements from a population?
A subset of measurements from a population is a smaller group of data points selected from the entire group of data points in the population. This subset is chosen to represent the overall characteristics of the larger population and is used for analysis or inference about the population as a whole.
How do you compute the point estimate of a population mean?
To compute the point estimate of a population mean, you take the sample mean. This is done by calculating the average of the data values in the sample. The sample mean is then used as an estimate of the population mean.
What are the similarities btn census and sample survey?
Both census and sample survey are methods used to collect data from a population. However, while a census attempts to gather information from every individual in the population, a sample survey collects data from a subset of the population. Both methods aim to provide insights and statistics about the population under study.
The facts collected during an experiment are called what?
The facts collected during an experiment are called data. Data can be quantitative (numbers and measurements) or qualitative (descriptions and observations) and are used to analyze and draw conclusions from the experiment.
