let us briefly discuss some of the important functions of statistics. 1. Presents facts in. simple form: Statistics presents facts and figures in a definite form. That ma…kes the statement logical and convincing than mere description. It condenses the whole mass of figures into a single figure. This makes the problem intelligible. 2. Reduces the Complexity of data: Statistics simplifies the complexity of data. The raw data are unintelligible. We make them simple and intelligible by using different statistical measures. Some such commonly used measures are graphs, averages, dispersions, skewness, kurtosis, correlation and regression etc. These measures help in interpretation and drawing inferences. Therefore, statistics enables to enlarge the horizon of one's knowledge. 3. Facilitates comparison: Comparison between different sets of observation is an important function of statistics. Comparison is necessary to draw conclusions as Professor Boddington rightly points out." the object of statistics is to enable comparison between past and present results to ascertain the reasons for changes, which have taken place and the effect of such changes in future. So to determine the efficiency of any measure comparison is necessary. Statistical devices like averages, ratios, coefficients etc. are used for the purpose of comparison. 4. Testing hypothesis: Formulating and testing of hypothesis is an important function of statistics. This helps in developing new theories. So statistics examines the truth and helps in innovating new ideas. 5. Formulation of Policies : Statistics helps in formulating plans and policies in different fields. Statistical analysis of data forms the beginning of policy formulations. Hence, statistics is essential for planners, economists, scientists and administrators to prepare different plans and programmes. 6. Forecasting : The future is uncertain. Statistics helps in forecasting the trend and tendencies. Statistical techniques are used for predicting the future values of a variable. For example a producer forecasts his future production on the basis of the present demand conditions and his past experiences. Similarly, the planners can forecast the future population etc. considering the present population trends. 7. Derives valid inferences : Statistical methods mainly aim at deriving inferences from an enquiry. Statistical techniques are often used by scholars planners and scientists to evaluate different projects. These techniques are also used to draw inferences regarding population parameters on the basis of sample information. (MORE)

In Science

Functions of Statistics: Statistics can be used for various purposes. 1) Simplification of mass data: Simplification of complex data and decision making for Managers has bec…ome easier by using various statistical concepts such as Sample, Population, Variance, Standard Deviation, etc. The Statistical concepts help in reducing the complexity of data and consequently in the understanding of the huge mass of data. 2) Easier Comparison: Statistical methods & Concepts makes collection of data easier which otherwise would have been difficult. The Various Statistical methods and concepts also helps in the Comparison of data thus collected from different sources. Grand totals, measures of central tendency, measures of dispersion, graphs and diagrams, coefficient of correlation all provide ample sources of comparison. Visual representation of numerical data like Pie Chart makes Comparison of data much easier and aids in effective decision making. 3) Brings out trends and tendencies in the data: After data is collected, it is easy to analyse the trend and tendencies in the data by using various concepts of Statistics. 4) Brings out the hidden relations between Variables: Statistical analysis helps in drawing conclusions / Inferences on data. Such analysis also helps in bringing out the hidden relations between Variable. 5) Decision making power becomes easier: With the proper application of Statistics and Statistical software packages on the collected data, managers can take effective decisions, which results in increased profitability of business. - Shashi (MORE)

Hi there this DUNESHKE folks the function of the Mechanical stage is to permit easy manipulation of the view of the specimen. Commonly, mechanical stages are equipped with t…wo transitional knobs, one for the X-axis and one for the Y-axis. Rotating these knobs allows minute and precise movement of the specimen within the field of view. Hope this was helpful Ask anything from Duneshke Bogoda on Facebook (MORE)

Statistical mechanics studies many particle systems in which only macroscopic quantities can be measured, quantum mechanics study dynamics of one or several elementary particl…es in which each measurement outcome is not deterministic but it is probabilistic. Both theories are probabilistic, but while statistical mechanics is based on classical probabilities, quantum mechanics has a peculiar probability structure (it is defined on probability amplitudes) that allows for the wave-particle duality.

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4 20c + 5 = 5c …+65 20c - 5c= 65 - 5.
15c = 60.
15c/15 = 60/15.
c = 4 (alternative method). (MORE)

They are completely different. Statistical functions are based onnumbers for things like averages, highest, lowest, count and manyother functions that statisticians use. Logic…al functions are basedon logic, comparing values to each other and doing things likefinding if things are less than or equal to each other. The IFfunction allows you to make decisions based on conditions. Youcould use it to determine if someone has passed an exam or not,depending on whether their marks have reached the pass mark or not.Some statistical functions have logical elements to them, such asthe COUNTIF function.

Some of the most commonly used functions in a worksheet arestatistical functions. These would include functions to getaverages, highest values, lowest values, amounts of value…s,frequencies and other things. So if you need to get any of thosethings, you would use statistical functions. There are a lot ofmore specialised statistical functions that would be used by peopledealing with statistics. So people doing statistical analysis orsurveys etc. would use the more specialised ones. (MORE)
