Several famous statisticians have defined statistics. Statistics definitions define statistics and their relevance.
Statistics is as old as mankind. Initially, statistical definitions were restricted to statecraft. “Statistics” is derived from the Latin phrase “status” and means “political state”.
The term statistics was originally used to collect data on historical and descriptive conditions. With increased usage, the term statistics today means much more. It is now utilized to analyze all types of data and methodologies. Statistic is defined in both one and plural terms.
the science of measuring, regulating, and communicating uncertainty.
Statistics – Singular
Statistics offers methods and principles for collecting, presenting, analyzing, and interpreting data. These strategies and ideas are also used to simplify complex data such that even a layman may grasp it.
Selligman defined statistics as a method and procedure for dealing with data from the initial step to the last stage of processing data. Statisticians collect, classify, present, compare, and analyse numerical data to shed light on any topic.
Turtle defined statistics as “the collection, classification, presentation, comparison, and interpretation of quantitative data.”
Statistics Plural Definition
Statistics is Numerical Data in Plural. Horace Secrist gives the perfect statistics definition in plural. He defines statistics as “the collection of data affected by a variety of factors, numerically stated, counted or estimated with reasonable precision, collected for a specific purpose, and arranged in connection to one another.”
Bowley defines very modest statistics in plural. He defined stats as
– “statistics are numerical explanations of facts set in relation to each other.”
What does the above statistics definition mean?
Statistics is the study of methods and procedures for collecting, analyzing, interpreting, and presenting empirical data. This makes it the most multidisciplinary field.
Statistics definitions have evolved along with the utilization of statistics.
The statistics definition heavily involves Uncertainty and Variation. That’s why statistics uses probability.
- statistics is a grouping of
The main characteristic of statistics is that it is a collection of facts. Statistics deals with data that can be related to time, place, and frequency. Statistics cannot study isolated facts since they are unconnected. For example, class averages are statistical data.
- It is heavily influenced by causes.
Also, statistical data are often tied to the social sciences and thus affected by a variety of circumstances. Since we can’t investigate one cause, we must study the cumulative effect of several causes.
- Statisticians use numbers.
Statistics definitions only deal with quantitative data. Statistically, data must be expressed numerically. Similarly, if qualitative data can be stated numerically, it is statistical data. That’s why statistics definitions refer to data rather than qualitative or quantitative data.
Data are estimated using Reasonable Standards of Accuracy.
Statistical data must be estimated according to their type and purpose. That’s why there’s no single standard for estimating data. Data should be estimated using Reasonable Standards of Accuracy (RSA).
- Systematic Data Collection-
Data definitions emphasize that reliable statistics can only be collected in a methodical manner. Depending on the statistical data, the Manner is systematic or not. Inaccurate data collection can lead to incorrect conclusions. Thus, accuracy is doubtful.
- Statistics is done for a reason
Before beginning the statistical technique, the statistician must have a purpose. If you don’t know why you’re gathering data, you’ll never know what procedures to use.
- Statistics must be related.
The statistics definition specifies that they must be able to be compared. You can only compare them if they are related, otherwise they are classified as heterogeneous data, and statistics can only be performed on homogeneous data.
The scope of statistics definition has evolved with the evolution of data handling methods and techniques. As stated above, statistics can be defined singularly or plurally. Almost all statisticians acknowledge certain statistical traits that can be understood using their statistics definitions.
