understand that stocks‚ forex‚ and commodities are or have been correlated in some way. For instance‚ prior to 2008 the United States Dollar had a direct correlation to oil‚ but now there is virtually no correlation. Gold on the other hand has a direct correlation. When gold is up the USD is down and vice versa. This is just a sample of the many correlations that have to be factored in to specific trades. Today there are multiple companies looking to bring on specific financial markets traders or clients

correlated‚ does that mean one thing is causing the other to happen? No. Just because things are correlated or related does not mean one will cause the other to happen. An example of a positive correlation is age and income; people who are older tend to earn more money. An example of a negative correlation is latitude and temperature; as latitude increases‚ temperature tends to decrease. 4. Describe an experiment requiring the statistic ANOVA for analysis.

whilst on tour of duty‚ detailed recordings were kept of each sailor’s health status. The recorded Life Change Scores were correlated with the sailor’s illness score. Findings: There was a positive correlation of + 0.118 between Life Change Scores and illness scores. Although the positive correlation was small‚ it did indicate that there was a meaningful relationship between LCU’s and health. As LCU scores increased‚ so did the frequency of illness. Conclusion: The researchers concluded that as

The throw with the fastest ball velocity was chosen to study. Ball velocity was determined by watching a video of the throw‚ and by dividing the distance of the neutral area by the time. The phases of movement were found by 2-D video. A Pearson correlation was used to determine if there was a relationship between the time spent in each phase of movement and ball velocity. What was found? [Steps 9 &10] A total of three phases of

Linear regression and correlation In linear regression‚ you should follows those instructions: 1. Choose one pair variables‚ first create the scatterplot (using Excel). Do this by simply plotting one variable as the x –axis and the other y-axis. Based on the scatterplot‚ comment on the relationship after fitting a simple curve‚ so you can be creative in pairing the variables. 2. Find the linear regression model by computing either manually or using Excel. 3. Compute the correlation

Spearman vs. Gardner Gardner’s theory of multiple intelligences suggests that there are seven different forms of intelligence. They are Linguistic intelligence which involves sensitivity to spoken and written language‚ the ability to learn languages‚ and the capacity to use language to accomplish certain goals. Logical-mathematical intelligence consists of the capacity to analyze problems logically‚ carry out mathematical operations‚ and investigate issues scientifically. In Howard Gardner’s

Charles Spearman is undoubtedly a prominent figure in the history of science‚ especially in terms of introducing statistical methods to psychology (Deary‚ Lawn & Bartholomew‚ 2008)‚ but also because of his impact on intelligence theories. This might be the reason why‚ unlike any other theorists of his time‚ his citation rates did not drop after his death‚ but actually are still increasing showing his undeniable contribution to the most recent scientific disputes (Jensen‚ 2000). Spearman was born
