Some context: Raymond Bernard Cattell (20 March 1905 - 2 February 1998) was a British and American psychologist, known for his psychometric research into intrapersonal psychological structure. His work also explored the basic dimensions of personality and temperament, the range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of abnormal personality, patterns of group syntality and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many multivariate research methods including the refinement of factor analytic methods for exploring and measuring these domains. Cattell authored, co-authored, or edited almost 60 scholarly books, more than 500 research articles, and over 30 standardized psychometric tests, questionnaires, and rating scales. According to a widely cited ranking, Cattell was the 16th most eminent, 7th most cited in the scientific journal literature, and among the most productive, but controversial psychologists of the 20th century.
Cattell noted that in the hard sciences such as chemistry, physics, astronomy, as well as in medical science, unsubstantiated theories were historically widespread until new instruments were developed to improve scientific observation and measurement. In the 1920s, Cattell worked with Charles Spearman who was developing the new statistical technique of factor analysis in his effort to understand the basic dimensions and structure of human abilities. Factor analysis became a powerful tool to help uncover the basic dimensions underlying a confusing array of surface variables within a particular domain.  Factor analysis was built upon the earlier development of the correlation coefficient, which provides a numerical estimate of the degree to which variables are "co-related". For example, if "frequency of exercise" and "blood pressure level" were measured on a large group of people, then intercorrelating these two variables would provide a quantitative estimate of the degree to which "exercise" and "blood pressure" are directly related to each other. Factor analysis performs complex calculations on the correlation coefficients among the variables within a particular domain (such as cognitive ability or personality trait constructs) to determine the basic, unitary factors underlying the particular domain.  While working at the University of London with Spearman exploring the number and nature of human abilities, Cattell postulated that factor analysis could be applied to other areas beyond the domain of abilities. In particular, Cattell was interested in exploring the basic taxonomic dimensions and structure of human personality. He believed that if exploratory factor analysis were applied to a wide range of measures of interpersonal functioning, the basic dimensions within the domain of social behavior could be identified. Thus, factor analysis could be used to discover the fundamental dimensions underlying the large number of surface behaviors, thereby facilitating more effective research.  As noted above, Cattell made many important innovative contributions to factor analytic methodology, including the Scree Test to estimate the optimal number of factors to extract, the "Procrustes" oblique rotation strategy, the Coefficient of Profile Similarity, P-technique factor analysis, dR-technique factor analysis, the Taxonome program, as well the Rotoplot program for attaining maximum simple structure solutions. In addition, many eminent researchers received their grounding in factor analytic methodology under the guidance of Cattell, including Richard Gorsuch, an authority on exploratory factor analytic methods.
What will it provide?
A: then intercorrelating these two variables would provide a quantitative estimate of the degree to which "exercise" and "blood pressure" are directly related to each other.

Some context: Edwin Washington Edwards (born August 7, 1927) is an American politician and member of the Democratic Party who served as the U.S. Representative for Louisiana's 7th congressional district from 1965 to 1972 and as the 50th Governor of Louisiana for four terms (1972-1980, 1984-1988 and 1992-1996), twice as many elected terms as any other Louisiana chief executive. He served a total of 16 years in office, the sixth-longest serving gubernatorial tenure in post-Constitutional U.S. history at 5,784 days. A colorful, powerful and legendary figure in Louisiana politics, Edwards, who has been dubbed the "very last of the line of New Deal Southern Democrats", was long dogged by charges of corruption. In 2001, he was found guilty of racketeering charges and sentenced to ten years in Federal prison.
Though arguably minor compared to the Edwards scandals of the 1980s and 1990s, the governor was embroiled in several ethics controversies during his first two terms in office. At the time, Edwards was remarkably candid about his questionable practices. When questioned about receiving illegal campaign contributions, he replied that "It was illegal for them to give, but not for me to receive." He also insisted he saw no problem with investing in a proposed New Orleans office building called "One Edwards Square" (it was never actually named that) while still governor, and demonstrated his gambling prowess to the press on one of his frequent gambling trips to Las Vegas. Later, Edwards' commissioner of administration Charles Roemer - father of future governor Buddy Roemer - was convicted of taking bribes and having connections with Mafia boss Carlos Marcello. Edwards managed to avoid direct implication in the Roemer case.  During the governor's first term, a disaffected former Edwards bodyguard named Clyde Vidrine made several high-profile accusations of corruption, including the sale of state agency posts. The accusations were investigated by a grand jury, but the Edwards administration attacked Vidrine's credibility and the investigation stalled. Later, Vidrine published a tell-all book called Just Takin' Orders, which included salacious details of Edwards' frequent gambling trips and extramarital escapades. Vidrine was murdered in December 1986 by the husband of a woman he was guarding, who believed Vidrine was having an affair with his wife.  In a 1976 scandal known as Koreagate, it came to light that Edwards and his wife Elaine had received questionable gifts in 1971, while Edwards was a U.S. representative. South Korean rice broker Tongsun Park was under investigation for trying to bribe American legislators on behalf of the South Korean government, and for making millions of dollars in commissions on American purchases of South Korean rice. Edwards admitted that Park gave Elaine an envelope containing $10,000 in cash, but insisted that the gift was given out of friendship and that there was nothing improper about it. In the course of the controversy, Edwards stated that he thought it was "super moralistic" for the U.S. government to prohibit American businessmen to accept gifts from foreign officials in the course of their business dealings. The scandal also engulfed Edwards's former congressional colleague Otto Passman of Monroe, who was later acquitted of all charges in the case.
