Most information services suffer from the requirement to perform better with fewer staff and resources. Therefore it is necessary for information managers to report on all their activities in order to be able to make effective claims for additional funding or to prevent further funding cuts. This book describes the different steps that are necessary to produce professional reports: data gathering (electronic or otherwise), sampling, graphical representation of data, summary statistics from data (including percentiles), confidence intervals for averages of data, comparison of two averages. Trend analysis (over time) and regression analysis are also discussed.
