et al. (1978) addressed this issue by calculating a Pearson product-moment correlation coefficient between primary (i.e. structured interview used for over 2 decades) and secondary raters (i.e. board certified psychiatrists with 9 and 4 years of experience). Researchers found that inter-rater reliability between the primary psychiatrist and the two other psychiatrists was .62. Because the reliability coefficient is relatively high, we can assume that the BDI is a reliable test to assess the…

little variation between student’s maladaptive perfectionism scores. 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…

provide weak positive linear relationships between the amount of time spent participating in extracurricular activities when compared to campus common assessment data. Table 8 depicts the weak positive relationship as it pertains to the correlation coefficient, ranging from +.20 to +.29, for a number of the comparisons between amount of time spent participating in extracurricular activities when compared to CCA results. When exploring the scatterplots further, Figures 1 and 2, the data points…

points scored increases, so does the total number of wins. On the other hand, the second scatter plot (Points Allowed vs. Total Wins) proves, as the points allowed increases, the total number of wins decreases. The calculation of the correlation coefficient (r) between points scored (x) and total wins (y) is 0.754 meaning that there is a strong uphill (positive) linear relationship between the two…

Introduction: The purpose of this study is to see if there is a link between the birth weight and gestation of newborn babies with smoking mothers and non- smoking mothers. The significance of this investigation is to find a relationship between the two as it might help with health benefits. The features in the investigation are the relationship between the two sets of data between the birth weight and the gestation period of smoking mothers and non-smoking mothers. Part A: The median for the…

positive correlation between the years of high school completed and the income of the respondent. The more years of high school that were completed led to a higher income for the respondent. This was calculated by a Pearson product-moment correlation coefficient. The values that were found were positive with r=0.208, n=906, p=0.000. This is summarized by the scatterplot above. The Sig value strengthens the argument for a positive correlation between years and school and a higher income level, as…

It was hypothesized that Communication Apprehension would correlate negatively with Affective Learning. The correlation coefficient r = -.082 (p = .293) indicates that the test scores are not significantly correlated. Although not significantly correlated, the hypothesis was partially supported as it correctly predicted the negative relationship between the two variables. The…

Method Participants We collected data from a sample of undergraduate students at the University of Colorado at Boulder. The students were all in an upper division course titled Research Methods in Psychology. The participants were between the ages of 18 to 32, with a mean age of 20.99 years and a standard deviation of 1.82 years. Out of the 208 students that we collected data from, 80 were male and 128 were female. In terms of class year, one was a freshman, four were sophomores, 98 were…

chosen are paying dividends quarterly, and make up 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…

A study was conducted to measure an individual’s attitudes towards homosexuality, attitude scales have been devised from Larsen et al in 1980 to LeMar and Kite’s 1997 attitude scale, to reflect modern day attitudes towards homosexuality a study was conducted using a new scale as the old one is outdated, using this new scale and additional study was conducted into the attitudes of an individual and the participant’s levels of religiosity to test the relationship between the two topics. Various…
