Test# 2: Name: Class ED-500 Introduction to Statistics Direction: Please circle the alphabet that describe your finial answer to the questions be 1) A graph that shows the pattern of the relation of two variables is a: low Page |1 A) histogram C) frequency polygon B) scatter diagram D) box plot 2) A correlation describes the relationship between two: A) equal-interval numeric variables Bscatterplots C) standard deviations Which of these statements is TRUE when drawing a scatter diagram? A) The highest number should start where the axes meet B) The variable that predicts the other goes C) The variable that predicts the other goes on the horizontal axis. D) The variable that is being predicted goes on the horizontal axis. What is the difference between a positive correlation and a negative correlation? A) D) horizontal axes 3) on the vertical axis. 4) In a negative córrelation high scores go with high scores and low with low; in a positive correlation high scores go with low scores and low with high B) In a negative correlation high scores go with low scores and low with high; in a positive correlation high scores go with high scores and low with low. C) Negative correlations are curvilinear, positive correlations are straight lines. D) Negative correlations represent a weak relationship; positive correlations represent a strong relationship The dots on a scatter diagram seem to form a straight line that goes upward to the right. This is called: A) a positive linear correlation C) a curvilinear correlation A researcher discovers that if people eat a certain fruit before a test, the more fruit eate better they do on the test. Beyond a certain point, however, the more fruit eaten the worse people test is an example of: A) a positive lincar correlation C) a negative linear correlation 5) B) a negative linear correlation D) no correlation 6) how well people do on the do on the test. The relation between amount of fruit eaten and B) a curvilinear correlation D) no correlation to your text, Mirvis and Lawler (197) found that the higher the level of job According he lower the level of absenteeism. Research on this topic has continued to show pattern all over the world and for university classes. B) cross-tabuler correlational this A) positive linear correlational C) correlational D)egative linear correlational alternatives best describes the pattern of scores on the scatter diagram below? zero-order 8) Which of the A) No correlation C) Positive linear correlation B) Curvilinear correlation D) Negative linear correlation
