Daily measurements of evaporation from the porous disk and Bellani plate atmometers, the Class A evaporation pan, and the Experimental Farms buried tank were compared and related to daily measurements of temperature, radiation, wind, and vapor pressure. Simple correlation coefficients indicated highly significant relationships among evaporation measurements (dependent variables) and the meteorological factors (independent variables) with the exception of wind.Multiple regression analyses showed highly significant correlations between each of the evaporimeters and the four meteorological variables studied. A linear combination of the four independent variables accounted for 70 to 86% of the variation in evaporation from the four evaporimeters, but the standard errors of estimate were also large. These four meteorological variables were of about equal importance in their influence on evaporation on the Canadian Prairies. Advected energy played a more important role than it has in more humid climates.

Evapotranspiration from irrigated alfalfa was related to evaporation from a Class A evaporation pan, an Experimental Farms buried tank, and a Bellani plate atmometer in addition to the meteorological variables temperature, sunshine, wind, and vapor pressure. Except for the evapotranspiration–wind relationship all simple correlation coefficients were significant when the crop was growing vigorously and completely shaded the ground.Although wind alone did not correlate significantly with either evaporation or evapotranspiration, it contributed appreciably when considered in combination with other meteorological variables. The limitations of simple correlation must be recognized in developing formulas intended for estimating evapotranspiration from meteorological data.

Studies that analyze the actions carried out by paddle tennis players during the point are scarce. The present investigation characterizes every action in which a stroke by a pair in a defensive position sends the ball over the position of a pair in an offensive position. It is a descriptive and observational study of quantitative methodology. The sample consisted of 1324 actions, statistical analysis units, from the women’s circuit in the 2018 World Padel Tour (WPT) season. For this study, various situational, dependent, and independent variables were analyzed. The results showed the number of times the categories of each variable occurred, as well as the significant relationships between the independent variable kind of hit and the dependent variables “actions that facilitate the possible change of position” (AFPCP) and “incidences in the game” (IG). The conclusion is that the lob is the most effective kind of hit (CSR = 4.9) to achieve the offensive position (CSR = 11.4), even if the point does not finish (CSR = 5.8), leading to more position exchanges during the same point in the AFPCP. These findings are of great interest since they give information about how and why certain behaviors produce a certain result.

This study examines the relationship between four independent variables (gender, age, reservation background, and cultural traditionalism) with three dependent variables (assessment of college, transition to college, and impact of college on an appreciation of Native heritage) among a sample of American Indian students attending a small, rural university. Findings include no significant relationships between any of the independent variables and the assessment of college. However, the transition to college is associated with age, reservation background, and cultural traditionalism while the impact of college on an appreciation of Native heritage is related to cultural traditionalism.

The Bender Visual-motor Gestalt Test and Beery's Developmental Test of Visual-motor Integration were administered to 51 educable mentally retarded boys ranging in age from 72 to 161 mo. These scores were compared with scores boys received on three gross motor tasks by computing simple correlation coefficients and multiple regression coefficients with Bender and Beery's tests as dependent variables. The simple rs were similar but order of inclusion of independent variables in the regression analysis suggests differences.

This article outlines the results of a study which investigates the perceptions of graduates regarding workplace expectations. A literature study provides a theoretical foundation which explains the nature of graduates’ workplace expectations. An empirical survey was conducted, using a self-administered questionnaire, which was completed by prospective graduates at two tertiary institutions. This sample was selected in terms of the proposed restructuring of higher education institutions. Eleven null-hypotheses, investigating relationships between the dependent and independent variables, are tested by means of specific statistical methods, such as analysis of variance and correlation coefficients. The results showed highly significant differences between workplace expectations of graduates (dependent variables) and classification data (independent variables). Specific guidelines are provided to ensure the creation of more realistic graduate expectations before entering the workplace.

Bagging Method

Traffic accidents are emerging as a serious social problem in modern society but if the severity of an accident is quickly grasped, countermeasures can be organized efficiently. To solve this problem, the method proposed in this paper derives the MDG (Mean Decrease Gini) coefficient between variables to assess the severity of traffic accidents. Single models are designed to use coefficient, independent variables to determine and predict accident severity. The generated single models are fused using a weighted-voting-based bagging method ensemble to consider various characteristics and avoid overfitting. The variables used for predicting accidents are classified as dependent or independent and the variables that affect the severity of traffic accidents are predicted using the characteristics of causal relationships. Independent variables are classified as categorical and numerical variables. For this reason, a problem arises when the variation among dependent variables is imbalanced. Therefore, a harmonic average is applied to the weights to maintain the variables’ balance and determine the average rate of change. Through this, it is possible to establish objective criteria for determining the severity of traffic accidents, thereby improving reliability.

The Relationship

Students without prior research experience may not know how to conceptualize and design a study. This article explains how an understanding of the classification and operationalization of variables is the key to the process. Variables describe aspects of the sample that is under study; they are so called because they vary in value from subject to subject in the sample. Variables may be independent or dependent. Independent variables influence the value of other variables; dependent variables are influenced in value by other variables. A hypothesis states an expected relationship between variables. A significant relationship between an independent and dependent variable does not prove cause and effect; the relationship may partly or wholly be explained by one or more confounding variables. Variables need to be operationalized; that is, defined in a way that permits their accurate measurement. These and other concepts are explained with the help of clinically relevant examples.

Abstract Longevity is increasing in what is called the centenarian society. However, the average retirement age of Korea is the lowest among OECD countries. Because of increasing longevity, older adults need activities after retirement. Volunteering can be a substitute that allows Korean older adults to find a social identity. This study examined older adults’ volunteering and how many kinds of volunteering affected relational satisfaction differently. This study used the 6th additional wave of the Korean Retirement and Income Study (2016). The target population of this study was ages over 60 and the sample size was 280. For data analysis, multiple regressions were used. Demographic variables were controlled. As for independent variables, reasons for volunteering whether they were motivated for self or for others were used. For dependent variables, relational satisfaction, such as family, human relation and overall life satisfaction was used. Volunteers’ health is an important factor for relational satisfaction. If volunteering was self-motivated, satisfaction of both family and human relations were negatively affected. Reason for others also affected satisfaction of family and human relations negatively. Volunteering initiated by others increased satisfaction of family and human relations. Doing more than one kind of volunteering affected both satisfaction of family and human relations. For overall life satisfaction, the effect of volunteering for oneself was lower than other reasons. These findings implied that reasons for volunteering affected relational satisfaction differently. In addition, the activities of volunteering, such as taking part in one or more had different effects.
