Statistical Data:
Statistical data science involves the collection, interpretation, and validation of data. It involves a variety of statistical operations performed with some statistical tools without having prior statistical knowledge. There are several software packages for performing statistical data analysis, including SAS (Statistical Analysis System), SPSS (Statistical Package for Social Sciences), etc.
There are Different Types of Statistical data :
- Numerical Data: The data can serve as a measure, such as a person's height, weight, IQ, or blood pressure, or they can serve as a count, such as the number of shares a person owns, a dog's number of teeth, or the number of pages in a book you finish before falling asleep.
2.Categorical data : Categorical data are attributes that can take on numerical values (such as the numbers "1" and "2" indicating male and female, respectively).
- Ordinary Data : In ordinal data, categorical data are mixed with numerical data. The data fall into categories, but the numbers placed on the categories have meaning. For example, rating a restaurant on a scale from 0 (lowest) to 4 (highest) stars provides ordinal data.
Statistical Methods:
It is a statistical method that extracts information from research data and provides ways to assess the robustness of research outputs with mathematical formulas, models, and techniques.
There are different types of Statistical Methods:
- Descriptive Methods : A descriptive method involves every step in the analysis and interpretation process, such as the collection of data, the tabulation of data, the measurement of central tendency, the measurement of dispersion, as well as the analysis of time series. This method is also otherwise called descriptive statistics .
2 Analytical methods : This method comprises all those methods which help analyze and compare any two or more variables. These include correlation analysis, regression analysis, attribute association analysis, and the like. This method is also referred to as analytic analysis.
-
Inductive Methods :A generalization procedure consists of all procedures that lead to an estimation of a phenomenon using random observations or partial data, such as interpolation and extrapolation. This methods is also otherwise called inductive statistics.
-
Inferential Methods :In other words, it is a method of drawing conclusions about the characteristics of a population based on samples of data. This method includes theories such as sampling theory, different tests of significance, statistical control, etc. This method is also otherwise called inferential statistics.
-
Applied Methods :These methods are used to solve real-life problems, such as statistical quality control, sampling surveys, linear programming, inventory control, and other procedures.

Are bar and pie charts part of nominal data?
They are part of nominal data if the study is about different kinds of methods for displaying statistical data.
What does statistical question mean?
A statistical question is one that anticipates variability in the data and seeks to gather information to analyze that variability. Unlike a simple question with a definitive answer, a statistical question typically requires data collection and statistical methods to answer. For example, "What is the average height of students in a school?" is a statistical question because it involves measuring and analyzing the heights of multiple students.
Why do managers need to know statistical methods?
because there are projects that include statistical methods.
When was Statistical Methods for Research Workers created?
Statistical Methods for Research Workers was created in 1925.
What is the purpose of using the seven basic statistical methods?
The seven basic statistical methods serve to summarize, analyze, and interpret data effectively. They help in identifying patterns, trends, and relationships within data sets, enabling informed decision-making. By employing these methods, researchers can draw meaningful conclusions, assess variability, and make predictions, ultimately enhancing the understanding of complex information.

What is the difference between statistical and non statistical?
Statistical refers to data or methods that involve quantifiable information, typically analyzed using mathematical techniques to draw conclusions or make predictions. In contrast, non-statistical encompasses qualitative data or approaches that do not rely on numerical analysis, often focusing on subjective insights, observations, or descriptive characteristics. Essentially, statistical methods aim for objectivity and generalizability, while non-statistical methods emphasize context and individual experiences.

Definition of numerical data?
Numerical data is data measured or identified on a numerical scale. Numerical can be analyzed using statistical methods, and results can be displayed using tables, charts, histograms, and graphs.
What are some uses for computational statistics?
It emphasizes the role of computation as a fundamental tool of discovery in data analysis, of statistical inference and for development of statistical theory and methods.
