Elementary stats builds on these topics:

1) Descriptive Statistics: Which describes data, mean, range.

2) Probability: The chance of something happening , like winning an election, finding, raining on a certain day.

3) Probability distribution: Studying data and graphs like normal distribution with bell curve.

SPSS:

We can use SPSS in the following areas

RUN FREQUENCIES.

CALCULATE DESCRIPTIVE STASTICS.

COMPARE MRANS

CONDUCT CROSS TABULATIONS.

RECODE DATA.

CREATE GRAPHAS AND CHARTS.

Do T-Testa.

Connduct ANOVAs

Run Various Type of Regressions.

Stastical methods involved in carrying out a study including planning, designing, collecting data, analysing, drawing meaningful interpretation and reporting of the research of the research findings.Thebstastical analysis gives meaning to the meaningless numbers, thereby breathing Life into lifeless data. The results and inferences are precise only of proper statistical tests are used. Stastics playing a major role in the field of research. Descriptive Statistics helps in the collection , analysis and presentation of data in a measurable form.Descriptive Statistics is one which describes the population. It is a branch of Stastics which concerned with describing population under study.

Inferential Stastics is used to make the generalisation about the population based on the samples.It is a type of Stastics, that focuses on drawing conclusions about the population.

In this discussion, you will apply the statistical concepts and techniques covered in this week's reading about correlation coefficient and simple linear regression. A car rental company wants to evaluate the premise that heavier cars are less fuel efficient than lighter cars. In other words, the company expects that fuel efficiency (miles per gallon) and weight of the car (often measured in thousands of pounds) are correlated. Performing this analysis will help the company optimize its business model and charge...
