قسمتي از مطالب تحقيق در مورد آمار :
آمار به عنوان يک علم، به بررسي دادهها و اطلاعات جمعآوري شده در موضوعات مختلف ميپردازد. اين دادهها ميتوانند از طريق نظرسنجيها، آزمايشهاي علمي، پژوهشهاي بازار و ساير منابع جمعآوري شده باشند.
Statistics help us to reach accurate results on various issues by analyzing these data. For example, statistics help us to analyze data collected about? A product, get results about marketing, pricing, product features and other various issues.
آمار به دو دسته تقسيم ميشود: آمار توصيفي و آمار استنباطي. آمار توصيفي، به بررسي و توصيف دادهها در قالب ميانگين، واريانس، مد، پراکندگي و توزيعهاي مختلف اطلاعات ميپردازد. اين نوع آمار بيشتر براي شناخت و توصيف دادهها به کار ميرود.
But inferential statistics are used to derive general results from the observed data and also to make decisions based on the observed data. This type of statistics is used for scientific research, experimental analysis, statistical modeling and risk analysis.
In statistics, probability distributions, mean, variance, sample error and other important concepts are used. Probability distributions show the probability of events as a distribution function. The mean shows the middle value of the data, while the variance is an indicator of the dispersion of the data. The sample error shows the difference between the mean of the sample data and the mean of the total data.
آمار چيست؟
Most people are familiar with the word statistics, which is used to record and display numerical information: the number of unemployed people, the daily price of some stocks in the stock market, the number of people lost due to the spread of a disease are examples of this concept. But this concept is not consistent with the main subject of statistics. Statistics mainly deals with situations in which the occurrence of an event cannot be definitely predicted. Statistical conclusions are often uncertain because they are based on incomplete information:
Estimating the current rate of unemployment in an area based on a daily study of several thousand people, or examining a new traffic plan based on asking the opinions of a number of people in a region are examples of this. Other cases of lack of certainty occur when repeated observations on a the phenomenon will give different results, even if we try to control the factors affecting the phenomenon that is to be observed. For example, not all one-year pine trees have the same height, even if they are of the same type of sapling and under the same light conditions. , air and soil are located.
آمار به عنوان يك موضوع علمي،امروزه شامل مفاهيم و روشهايي است كه در تمام پژوهشهايي كه مستلزم جمع آوري داده ها به وسيله يك فرايند آزمايش و مشاهده و انجام استنباط و نتيجه گيري بوسيله تجزيه و تحليل اين داده ها هستند،اهميت بسيار دارند.
تعريف آمار:
Statistics is a set of concepts and methods that are used in any field of research to collect and interpret relevant information and make conclusions, in conditions where there is no certainty and change. The equivalent of the word statistics in English is "statistics", which historically The Latin word "status" is derived and one of the meanings of the last word is "state".
