ENGINEER'S NEW OUTLOOK TOWARDS STATISTICS

"Being an engineer i have always looked at statistics as a tricky subject to understand! But the software changed my perspective towards the subject."

SPSS Statistics (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.

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: 1,2,3....... Its linear regression

·         Prediction for identifying groups: Factor analysis, cluster analysis (two-step, K-means, hierarchical), Discriminant

Monovariate Analysis:

The analysis is carried out with the description of a single variable in terms of the applicable unit of analysis. For example, if the variable "age" was the subject of the analysis

Bivariate Analysis:

 It involves the analysis of two variables (often denoted as X, Y), for the purpose of determining the empirical relationship between them.

Common forms of bivariate analysis involve creating a percentage table or a scatterplot graph and computing a simple correlation coefficient.

 

Multivariate analysis (MVA) is based on the statistical principle of multivariate statistics, which involves observation and analysis of more ...

Problems involved:

Analysis,observing,interpretation,strategy

Types of variables:continous continous variable,continous discrete variable

To begin the process of adding data, just click on the first cell that is located in the upper left corner of the datasheet. It's just like a spreadsheet. You can enter your data as shown. Enter each datapoint then hit [Enter]. Once you're done with one column of data you can click on the first cell of the next column.han one statistical outcome variable at a time.

[Type] One can specify whether the data are in numeric or string format, in addition to a few more formats. The default is numeric format

Data can be measured in 4 ways

A)NOMINAL-These are meaningless numbers in which there is no rational reason,eg-numbers written on back of  t-shirts of cricket players, vehcile registration number

B)ORDINAL-These numbers have a logical order but magnitude of difference between them unknown,eg- top 10 richest businessmen in the world

C)SCALE- It has order as well as magnitude and difference between them is known eg- Age difference

D)RATIO- It is the Highest level of measurement. order,magnitude of difference known,have absolute zero,ratio of two numbers is meaningful.

[Labels] Using the labels option can enhance the readability of the output. A variable name is limited to a length of 8 characters, however, by using a variable label the length can be as much as 256 characters. This provides the ability to have very descriptive labels that will appear at the output.

Once data has been entered or modified, it is adviseable to save. In fact, save as often as possible [File => SaveAs].
