Correlation and dependence

to 6.557% of S&P 500 as of today. From 2011 until today we see that our portfolio has had, return-wise, a similar performance to the S&P 500 with around 11% annual returns. Also, the correlation coefficient of 0.85 tells us that our portfolio is highly correlated to the S&P 500 index. Both returns and correlation can be explained by our stock picks. WFM, AAPL, XOM, C, and JWN have significant weights in the S&P 500 index. Interestingly, our portfolio had volatility of 1.23%, measured by…

euphoria, increased energy/alertness, and suppression of hunger. Examples of negative reinforcement, which often is a result of chronic use, which factors may be depression, paranoid psychosis, confusion, exhaustion, and a strong psychological dependence. There are many undesired acute affects that may result in the consumption of cocaine, this includes increased heart rate/blood pressure/breathing, increased body temperature resulting in excessive sweating, vasoconstriction, insomnia, panic,…

that showed a statistically significant correlation with the ToM results from the second wave of testing, were shyness/withdrawal, perceptual sensitivity, and aggression. None of the other tested traits had statistical significant correlation to ToM, but attentional focusing had a positive correlation to the block test and IC, while activity level had a negative correlation to IC. Both shyness/withdrawal and perceptual sensitivity showed a positive correlation with the development of ToM, while…

1. QUESTION: Class, what does the correlation coefficients of -1, +1, and 0 tells you about the relationship between the two variables? It depends on the method one uses, but the Pearson correlation coefficient is the most widely used. Values in the form of numbers show the direction and how strong the relationship is between two different variables. These can range from -1.00 up to +1.00. If it is positive it is a direct relationship. For example, if one increases the other will also increase…

interest (continuous), two correlations tests were performed. Hypothesis One: Correlations Test A sample of n = 63 subjects was obtained with scores on Communication Apprehension (M = 3.00, SD = 1.54) and Academic Performance (M = 2.13, SD = .96). It was hypothesized that Communication Apprehension would correlate negatively with Academic Performance.…

who felt they belonged and had some sort of connection with others overall had better self-esteem, as well as a better mental state, such as lower symptoms of depression (Dang, 2014). The purpose of this study was to see if there is a positive correlation between self-esteem and social inclusion by measuring self-esteem and friendships. In 1999, Professor Mark Leary introduced sociometer theory. Sociometer theory is a psychological gauge or meter that monitors the degree in which other people…

Computer exercise one and two Nominal level data was identified based on the parameters that it is mutually exclusive and exhaustive. It cannot be ranked but it maybe assigned a number such as one or two for classification purposes Burns, Grove, Gray (2013), Using the bladder study provided in SPSS, nominal level data were identified as, education level, ethnicity, zip code and marital status. Two modes were identified from the nominal level data. For ethnicity the mode was African American (n…

A correlation coefficient was calculated between procrastination and adaptive perfectionism scores (r (523) = -.14, p < .001). A significant negative correlation was found. This supports our first hypothesis and suggests it was correct in stating that those scoring high in procrastination would score low in adaptive perfectionism. A correlation coefficient was calculated between procrastination and maladaptive perfectionism scores (r (523) = .36, p < .000). A significant positive…
