With the inclusion of real-world data and a host of health-related examples, this is an impressive introductory statistics text ideal for all health science and nursing students. Health and nursing students can be anxious and lacking in confidence when it comes to handling statistics. This book has been developed with this readership in mind. This accessible text avoids using long and off-putting statistical formulae in favor of non-daunting practical and SPSS-based examples. What’s more, its content will fit ideally with the common course content of stats courses in the field.
Chapter 5: Summary Statistics for Continuous Data
Summary Statistics for Continuous Data
Once the data are entered into SPSS it is good practice to plot continuous data; data that are either continuous or discrete and then obtain some descriptive statistics. These may reveal data that have not been entered correctly, and therefore need checking before further analysis can be carried out. For example, those who appeared over 100 years old may warrant further checking with the data collection sheet or the original source as there are few people in the population that old. Individual variables can be plotted using histograms. Histograms will also reveal the distribution of variables; useful for descriptive purposes and to determine which statistical tests are appropriate. Statistical tests are explained further in later chapters.
