Such instances are usually observed in data relating to economic and business situations. Check 8 / 19 is the line which gives the best estimate of one variable for any given value of the other variable Check 9 / 19 _______________ formula can be used even when dealing with variables which are measured quantitatively pearman‘s rank correlation Spearman‘s rank correlation Rank Spearman‘s rank correlation 10 / 19 ______________ is a type of regression in which more than two variables are studied Dependent Variable Simple Regression Regression analysis Independent Variable 11 / 19 _____________ describes a situation where for a unit change in one variable there is a constant corresponding change in the other variable over the entire range of values. Linear Correlation Correlation Linear Near Correlation 12 / 19 in general sense, means the estimation or prediction of the unknown value of one variable from the known value of the other variable Check 13 / 19 A British Psychologist _______ developed a formula in 1904 which can be used to obtain the correlation coefficient between the ranks of n individuals in the two variables or attributes being study Charles Edward Spearman Alfred Sumer Elijah Harmer Edward Spear 14 / 19 ______ Situations may arise when the values of two variables deviate in the same direction correct correlation Positive correlation Negetive correlation 15 / 19 Karl Pearson was a British Biometrician and statistician suggested a mathematical method for measuring the magnitude of linear relationship between two _____ Check 16 / 19 Which of the followings is not a type of system?
