Correlational Design

This study is a correlational design with the aim of finding out if there is any  positive correlation between the students’ interest in reading poetry and their  ability to analyze poetry at SMA Kartika I-2 Medan. The study was conducted at SMA Kartika I-2 Medan. The product moment correlation formula was used to determine the correlation between the students’ interest in reading poetry and their  ability to analyze poetry.  The hypothesis was tested by comparing the value of  rcount to rtable on the degree of freedom (df) = 30 - 2 = 28 with α = 0.05 significance level and df = 28 (0.361). It was found that  rcount was higher than rtable  (0.726> 0.361), and thus null hypothesis was successfully rejected. The result of the study shows that  there was any positive correlation between the students’ interest in reading poetry and students’ ability to analyze poetry at the eleventh grade students of SMA Kartika I – 2 Medan. The correlation coefficient was 0.726, and the regression line was Y = 12.07 + 0,948x. The contribution of the students’ interest in reading poetry to their ability to analyze poetry is 47.29%. Keywords: Ability, Analyze, Correlation, Interest, Poetry

Before And After

Using the 133Xe-DSPECT technique, quantitative measurements of regional cerebral blood flow (rCBF) were performed before and after provocation with acetazolamide (Diamox) i. v. in 32 patients without evidence of brain disease (normals). In 6 cases, additional studies were carried out to establish the time of maximal rCBF increase which was found to be approximately 15 min p. i. 1 g of Diamox increases the rCBF from 58 ±8 at rest to 73±5 ml/100 g/min. A Diamox dose of 2 g (9 cases) causes no further rCBF increase. After plotting the rCBF before provocation (rCBFR) and the Diamox-induced rCBF increase (reserve capacity, Δ rCBF) the regression line was Δ rCBF = −0,6 x rCBFR +50 (correlation coefficient: r = −0,77). In normals with relatively low rCBF values at rest, Diamox increases the reserve capacity much more than in normals with high rCBF values before provocation. It can be expected that this concept of measuring rCBF at rest and the reserve capacity will increase the sensitivity of distinguishing patients with reversible cerebrovascular disease (even bilateral) from normals.

Uniformly Most Powerful

Abstract Regions of differing constraint, mutation rate or recombination along a sequence of DNA or amino acids lead to a nonuniform distribution of polymorphism within species or fixed differences between species. The power of five tests to reject the null hypothesis of a uniform distribution is studied for four classes of alternate hypothesis. The tests explored are the variance of interval lengths; a modified variance test, which includes covariance between neighboring intervals; the length of the longest interval; the length of the shortest third-order interval; and a composite test. Although there is no uniformly most powerful test over the range of alternate hypotheses tested, the variance and modified variance tests usually have the highest power. Therefore, we recommend that one of these two tests be used to test departure from uniformity in all circumstances. Tables of critical values for the variance and modified variance tests are given. The critical values depend both on the number of events and the number of positions in the sequence. A computer program is available on request that calculates both the critical values for a specified number of events and number of positions as well as the significance level of a given data set.

Abstract The author seeks an answer to the question whether a higher intensity of tourism movement is connected with a higher share of tourism in the economy in selected tropical island territories. With the use of the Spearman correlation coefficient, the existence of the average positive correlation between the intensity of tourism movement and the share of tourism in the economy has been determined. In the second part of paper, the author looks at the conditions which affect the role of tourism in the economy in proportion to the intensity of tourism movement. For this purpose, the Chi-square test and detailed case studies of chosen tropical islands are discussed.

The study aims at finding out the relationship between students’ interest and their reading comprehension level in short passages. This study was conducted at the second grade of Senior High School 10 of Gowa. The population of this study was all of the students in academic year 2019/2020 which consisted 265 students, and the sample was 30 students selected by using purposive method. The researcher applied correlational design. The researcher used the instrument to obtain the data, they were questionnaire and test. The scores from both instruments were calculated and analyzed by using statistical procedure of Product Moment Correlation to find out whether there was a correlation between the two variables or not. The result showed that there was low correlation with the index value of correlation coefficient (rxy) of 0.28. Furthermore, the hypothesis testing showed that the index value of correlation coefficient (rxy) of 0,28 was lower than the index value of correlation coefficient of the Product Moment table (rt) of 0,306 which meant that, the null hypothesis (H0) was accepted and alternative hypothesis (H1) was rejected. Therefore, students’ interest in short reading comprehension passages is in average level because only a few students are interested in English lesson especially those who have high interest and many vocabularies to learn English. Short Passages did not give a big impact on students’ interest and their achievement in reading comprehension because of some factors. There is not self-interest in reading, lack of vocabulary and support parents and all of school elements in order to improve the students’ reading interest optimally. The findings of this study might be used as the input for both teachers and students to improve students’ reading comprehension level.

Attachment is a deep and enduring emotional bond that connects one person to another across time and space. Assertiveness can be defined as the ability to express one’s own thoughts, feelings, and beliefs in an explicit and appropriate manner, and to show respect for other’s rights while protecting one’s own. The present quantitative study uses a between group design to study the differences between male and female college students with respect to levels of parent attachment, peer attachment and their dimensions (viz., trust, communication and alienation) and assertiveness. The relationship between mother attachment, father attachment, peer attachment and assertiveness was analysed in both the groups using a correlational design. Purposive sampling was used to collect the data from male (N=200) and female (N=200) college students. Inventory for Parent and Peer Attachment and Rathus Assertiveness Schedule was used. Independent t-test results indicated no difference between males and females with respect to parent attachment, peer attachment and assertiveness. Correlation results indicated a significant positive relationship between assertiveness and the dimensions trust and communication of mother attachment. There was a negative correlation between assertiveness and trust of father attachment and a positive correlation between assertiveness and alienation of father attachment. A negative correlation between assertiveness and the dimensions trust and communication of peer attachment and a positive correlation between assertiveness and alienation of peer attachment were also indicated with correlation. Results also revealed difference in the levels of assertiveness among college students having dominant mother, father or peer attachment. The present study reiterates earlier findings on attachment. Assertiveness in college students could help them build their individual character and personality and help in interpersonal interactions.
