Answer to Question 1

Pearson Product Moment correlation coefficients are the most commonly reported correlations and are designated as r. They range from an anchor point of -1.0 to immediately below 0 for negative correlations, and from immediately above 0 to an anchor point of +1.0 for positive correlations. An r = 0 indicates the absence of a relationship. The absolute value of the correlation coefficient indicates the strength of the relationship and the sign indicates the nature of the relationship.

Answer to Question 2

Correlational studies (also called observational studies) describe the magnitude of covariation between stress and illness but do not give sufficient information to determine causation. In other words, they only give us information about the nature and strength of the relationship and not its causal relations. Correlation coefficients may be used to summarize the relationship between variables found in correlational studies.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
