Example text
Predictions are made and compared to the data. Overall there is much variation which cannot be accounted for by the model, and a statistical analysis is concerned with making inferences and decisions in the presence of variability. Without the variation there would be little need for statistical ideas, but as this variation is pervasive there is much need for good statistical analysis. Chapters: graphs, relationships, linear regression, correlation, estimation, probability models, significance testing.
In terms of the scales of measurement on which the variables are recorded there is a clear order. Nominal variables are measured on a nominal scale where only the name is important and there is no concept of order or size or distance. Ordinal variables are recorded on an ordinal scale where there is a concept of size but not of distance. Thus with a variable recording the degree of satisfaction at three levels - unsatisfied, satisfied, very satisfied - we know that satisfied is better than unsatisfied but not how much better.
A good presentation of the results, often in a clear graph or table, will always assist the interpretation and utility of the statistical analysis. Statistical models pervade the whole process, and they are in the background of all the work in this book. The correct interpretation of the data will depend upon the correct model being used. The models are normally probability models which provide information on the chances that certain observations are made or on the values which are expected to occur.
