SPSS Statistics is a software package used for statistical analysis. It is now officially named "IBM SPSS Statistics". Companion products in the same family are used for survey authoring and deployment (IBM SPSS Data Collection), data mining (IBM SPSS Modeler), text analytics, and collaboration and deployment (batch and automated scoring services).

SPSS (originally, Statistical Package for the Social Sciences, later modified to read Statistical Product and Service Solutions) was released in its first version in 1968 after being developed by Norman H. Nie, Dale H. Bent and C. Hadlai Hull. SPSS is among the most widely used programs for statistical analysis in social science. It is used by market researchers, health researchers, survey companies, government, education researchers, marketing organizations and others. The original SPSS manual (Nie, Bent & Hull, 1970) has been described as one of "sociology's most influential books".[1] In addition to statistical analysis, data management (case selection, file reshaping, creating derived data) and data documentation (a metadata dictionary is stored in the datafile) are features of the base software. SPSS was released in its second version in 1972 and its company name is INDUS Nomi. Statistics included in the base software:

Descriptive statistics: Cross tabulation, Frequencies, Descriptives, Explore, Descriptive Ratio Statistics Bivariate statistics: Means, t-test, ANOVA, Correlation (bivariate, partial, distances), Nonparametric tests Prediction for numerical outcomes: Linear regression

Prediction for identifying groups: Factor analysis, cluster analysis (two-step, K-means, hierarchical), Discriminant The many features of SPSS are accessible via pull-down menus or can be programmed with a proprietary 4GL command syntax language....

a) Develop a 99 percent confidence interval for the mean selling price of the home.
b) Develop a 95 percent confidence interval for the mean distance of the home is from the center of the city.
Exercise 02
a) A recent article in Bangladesh Observer indicated that the mean selling price of the homes in the city of Dhaka is more than Tk. 2200. Can we conclude that the mean selling price in the Gulshan area is more than Tk. 2200? Use the 0.01 significance...

1.) IBM advertises itself as a company that provides service and business solutions. It used to be positioned as a computer hardware company, but as more companies like HP and Dell began to pop up they were forced to move away from this image. I recently had the pleasure of speaking with an IBM sales person, and he said that they very much rely on the value of their products, rather than competing on price. IBM...

...assigned to find interval estimates for a population mean and a population proportion.
b) Is finding an interval estimate an example of inferential or descriptive statistics? Explain.
It is an interval estimate is an example of inferential statistics, as an estimate of the value of the population parameter is made based on sample statistics.
c) An interval estimate (23.8, 30.6) is determined for the mean age of NSCC students. Identify the point...

...What are the characteristics of a population for which a mean/median/mode would be appropriate? Inappropriate?
The analysis of data begins with descriptive statistics such as the mean, median, mode, range, standard deviation, variance, standard error of the mean, and confidence intervals. These statistics are used to summarize data and provide information about the sample from which the data were drawn and the accuracy with which the sample represents the...

...Statistics: Application of Statistics in Today’s Society
Statistics is the collection of data and its representation or interpretation. It is used to analyze what is happening in the world around us.

Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration...
