Statistical elements are the basic parts that underlie the data set in the form of numbers or non-numbers arranged in the form of tables or diagrams that describe or relate to a particular problem. This time matematikaakuntansi.blogspot.com will explain about 4 statistical elements.
1. Population
Population in statistical science is a set of data that has the same characteristics that identify a particular phenomenon or event. Population is a basic problem in statistics. Population is also not just the number of objects or subjects that are studied, but includes all the characteristics, properties possessed by the object or subject.
Example of Population
The following examples of the population are:
The human population in the country of Indonesia
Fish population in the river
And others
2. Sample
The sample in statistics is a collection of data taken or selected from a population. Sampling of a population aims to make a reduction of the quantity of objects studied, generalize the results of research, and highlight the general characteristics of the population.
There are three kinds of advantages if we do sampling of them, are:
- Save money
- Data collection is faster
- Nine samples can ensure uniformity and to improve the accuracy and quality of data because the data set is smaller.
3. Inference Statistics
Inference statistics are a decision, approximation or generalization of a population based on the information contained in a sample. This means that inferential statistics is a data analysis technique used to determine the extent to which the similarity between the results obtained from a sample with the results to be obtained in the population as a whole.
4. Measurement of Reliability
Measurement of reliability is a measurement of the consequences of possible bias of data after inference. It is necessary to measure the reliability so that data refraction does not occur. Reliability test is done to know the internal consistency of all data in a set of questionnaires
