Statistical analysis SPSS statistical system –
running Statistical analysis and the SPSS statistical system A wide range of areas of daily life in terms of business and the various tasks associated with the nature of each work. Where there is an urgent need for statistical data in commercial, financial, educational and even industrial businesses, which require collecting and analyzing all information in an accurate and scientific manner, with specific proportions and mathematical operations to give a clear and understandable numerical formula to employers. Especially in the jobs of companies and establishments, which are based on conducting surveys about population groups and human resources and taking samples from them in accordance with their work methodology and what provides successful future studies about them. In view of the importance of statistics and its multiple uses that organize the massive data and show it in a clear and legible manner, we have prepared this article through Our trading platform. Let us learn through it in detail what statistical analysis is, its various types, methods of use, important benefits, and other details related to this topic.
What is statistical analysis
statistical analysis Statistical analysis: It is a branch of science that provides various analytical tools and techniques to deal with the huge volume of data. In other words, it is the process of collecting, classifying, analyzing, interpreting, and showing the final digital forms of data. With the aim of making conclusions about populations, starting from the selected sample data that can be used by business experts to solve their problems.
In addition, statistical analysis relies on identifying patterns and trends, removing bias and preparing for decision-making. It is also a distinct business intelligence tool based on collecting and examining business data and reporting on trends. Most companies also use this strategic choice to identify their best-performing product lines, identify underperforming sales staff, and learn how sales performance varies between different regions of the country.
On the other hand, types of statistical analysis can help predictive modeling work. Rather than showing simple trend predictions that can be affected by a number of external factors, statistical analysis tools allow companies to dive deep to discover additional valuable information.

The importance of statistical analysis
The importance of statistical analysis from its prominent role is as follows:
- Assist in collecting, classifying and analyzing data, regardless of its size.
- Providing real and accurate notifications to companies, government and private institutions that depend on statistics in their workflow.
- As well as relying on statistical analysis in the scientific, medical and commercial fields, and its participation in making a basic future decision for the party that relies on it.
Types of statistical analysis
The main types of statistical analysis include:
- Descriptive statistical analysis.
- Inferential statistical analysis.
- Prospective analysis.
- Descriptive analysis of the data.
- Exploratory Data Analysis EDA.
- Causal analysis.
- Automated analysis.
Descriptive statistical analysis
It is considered one of the most important types of statistical analysis, as it relies on organizing and summarizing data using numbers and graphs, assuming that it is for the entire population. With the aim of facilitating the inventory and counting of the huge amounts of data and their interpretation clearly without forming conclusions that go beyond the analyzes or responding to any other hypotheses. This type also includes various operations such as scheduling, and measuring central tendency (average, median, mode). Also measure of dispersion or variance (range, variance, standard deviation) and deviation for measurements and time series analysis.
Inferential statistical analysis
Inferential statistical analysis is used directly when examining each unit of the population is not achievable, and then presents the information obtained to the entire population. This type of statistical analysis also allows testing a hypothesis based on a sample of data from which conclusions can be drawn by applying probabilities and making a generalization about the entire data. Thus conclusions can be drawn regarding future outcomes that go beyond the available data. Thus, samples and tests of direct importance are taken for the final statistical judgment.
Future statistical analysis
Futures analysis is used to predict future events, based on current and past facts and figures. It draws on statistical techniques and machine learning algorithms to describe the possibility of future outcomes, behaviors, and trends. This is based on recent and past data. The techniques used in this field also include deep data search and modeling. Also, artificial intelligence, machine learning, and other technologies expected in the future.

Descriptive analysis of the data
Descriptive analysis examines data to find out exactly what is needed. This is to be widely used in business analysis in order to choose the best possible procedure that suits it. A further statistical analysis of exclusions is published to provide the actual answer. The main focus is on discovering the optimal proposal for the decision-making process. For your information, descriptive analysis implements many techniques, the most important of which are:
- Graph analysis.
- Also algorithms.
- Handling complex events.
- So is machine learning.
- Recommendation engine.
- and business rules.
Exploratory Data Analysis EDA
Exploratory data analysis (EDA) is also an important type of statistical analysis. It is a direct analogue of inferential statistics, and is implemented by seasoned data experts. For your information, this type focuses on analyzing data patterns to identify potential relationships. EDA can also be contacted to discover unknown associations within the data, and to examine missing data from previously collected data. To get the most out of potential future visions, examine assumptions and hypotheses.
Causal statistical analysis
Causal analysis helps in understanding and identifying the reasons behind the questions of things and finding their various causes and justifications. This type is widely used in the field of information technology to check the quality assurance of a particular program, and find out why this program failed, whether there was an error, data breach, etc. Thus, it constitutes a real and reliable preventer for companies from falling into direct setbacks.
Automated statistical analysis
This type of statistical analysis is less common, however, and is used in the process of big data analytics and the biological sciences. This is with the aim of spreading it, understanding and explaining how things happen, rather than how specific things happen in a camouflaged and unclear way. Further to understand individual changes in variables that cause changes in other variables in return excluding external influences and considering the assumption that the entire system is affected through the interaction of its internal elements.
What is the SPSS Statistical System?
It is considered SPSS statistical system It is an assistant for statistical analysis, and it is one of the most important approved programs for the implementation of statistical and analytical operations. It includes a package of lists and tools through which data is entered, analyzed, and accurate numerical results are shown. It also provides data transformation, infographics, and direct marketing features for seamless data management. In the context of this, SPSS is used in many basic areas, including the following:
- Scientific research.
- Survey companies.
- Educational research.

Methods of statistical analysis
Statistical analysis is carried out in several ways approved by companies and governmental and private agencies, as follows:
- Statistical mean method.
- standard deviation method.
- Undo method
- hypothesis testing method
- Method for determining sample size.
Statistical mean method
It is one of the most common methods of statistical analysis, as it is used in exploration and mathematics. It is based on determining the general pattern of the data set. Including the ability to get a quick and focused perspective of the data. In addition, the determination of data averaging requires the following:
- Add all numbers.
- Then divide the total result by the number of numbers within the available data set and obtain the correct estimated statistical result.
standard deviation method
Standard deviation is a strategy of statistical analysis methods that measure the spread of information about a mean. This skew also focuses on information that is more widely spread out from the mean. Also a low standard deviation shows that most of the information is the mean and can also be known as the expected value of the group.
Regression is the direct link between the independent variable and the dependent variable in statistical analysis methods. It also represents the line used in graphs and graphs for regression analysis. Whether the links between the factors are strong or weak, despite showing patterns over a given time period. However, this method is flawed because it does not fully explain the error.
hypothesis testing method
Hypothesis testing known as the T-test is one of the important methods of statistical analysis. This method of hypothesis testing relates to testing whether there is a conflict or a certain valid end to the data set. It takes into account the comparison of information with different assumptions and hypotheses. It can also help assess what the choices made could mean for the business.
Method for determining sample size
This method of statistical analysis is concerned with examining information for statistical methods. Especially in some cases where the data set is quite massive and essential. This makes it difficult to collect accurate information for each component of the data set. In order to find the sample size, the following points can be relied upon:
- Use a fairly small sample size.
- Also use a minicomputer that fits the sample size.
- Use a preexisting table to determine your sample size.

The adoption of statistical analysis in different companies and establishments has many benefits and advantages, which are as follows:
- Reducing operating costs and rationalizing spending more accurately than before by developing future insights through correct data analysis.
- As well as a deep analysis of the market, including the sales movement, and focus on the targeted products and the mechanisms used in the marketing process.
- Also, enhancing workplace efficiency and motivating employees to perform better and more productively.
- Improve decision-making and the ability to make informed and correct decisions.
At the end of our article, these were the most prominent ideas about Statistical analysis and the SPSS statistical system. Through it, we reviewed the most important types of statistical analysis, its methods of use, its benefits, and its importance in the labor market. Especially for the entities that have a direct relationship with population surveys and conducting questionnaires, where the role of statistical analysis was and still is clear and tangible in anticipating studied results and providing clear insights on which to rely on in adopting decisions that touch the reality of work.
