According to this data, it is classified as a correlation.a. strong positiveb. weak positivec. moderate positive2- The correlation coefficient for two variables was: r = -0.253. According to this data, it is classified as a correlationa. Poor or weak negativeb. invalid or nonexistentc. moderate negative3- It is used in order to predict the values of a dependent variable based on the values of at least one independent variable.a. scatterplotb. determination coefficientc. Correlation Analysis4- The independent variable is plotted on the axis "x" and dependent on the axis "y"a. Correlation Analysisb. Regression Analysisc. scatterplot5- It is equal to the sum of the squares regression of the sum of squares totala. scatterplotb. determination coefficientc.
