Pearson product-moment correlation coefficient

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…

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.…

Introduction Employee engagement is a workplace tactic that brings about the ideal conditions for all associates of an organization to: excel each day, commit to their companies’ goals, and be driven to contribute to the organization’s success. Employee engagement can be measured and can vary from poor to great. Nurturing employee engagement in the workplace can also deepen communication between members of an organization and increase the overall productivity. The purpose of this study is to…

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…

that build support and fight assessing with females was significant at -.801, sig. =.001, n=13 and the males Pearson correlation was at .011, sig. 971, n =13. The next result concluded the correlation between the questions (before build participation at risk behavior and crime assessment effective), the males had a Pearson correlation at -.601, sig.030, n=13 and the females Pearson correlation was at .103, sig .738,…

the scores of the 15 items. The scores could range from a low of 15 to a maximum of 75. Upon analyzing the result, the Spearman rank-order correlation test shows that there was a significant positive relationship between the participants’ global competence score and the language learning motivation score. For the four categories of motivation, the correlation for integrativeness was 0.302, for Instrumental orientation was 0.312, for attitudes and beliefs was 0.260, and for parental encouragement…

2.6 were used. Correlation was done between area averaged TWS of each region and sea surface temperature indices of major global oceans (Pacific Ocean: from different Niño regions such as Niño 1.2, Niño 3, Niño 3.4 and Niño 4; and Indian Ocean SST, DMI). The Pearson product moment sample coefficient of correlation was used, which is defined as: ………………………………………….……...….…3.17 Where is correlation coefficient formally called Pearson product moment sample coefficient of correlation,…
