independent and dependent variable

An experiment to show that the vertical and horizontal motions of a body are independent of each other Place two coins A and B near the edge of a table as shown in the figure. Simultaneously drop the coin A vertically and flick the coin B horizontally. After a while we will hear just ..

The means of each group of a two-way analysis of variance for two independent variables are plotted and shown in the three graphs. Which of these represents an ordinal interaction? Consider the interaction to be significant. => Graph 2 or Both graph 1 and graph 2 or Graph 3 or G..

A bag contains some red colored and blue colored marbles. First a red colored marble is drawn and then without replacing the first marble, a blue colored marble is drawn. Are the two events dependent or independent? => Dependent or Independent..

The mass of the oscillating particle The force constant of the spring (or any other agency) which supplies the restoring force. The above equation tells us that period is independent of the amplitude. Such a motion is said to be isochronous..

By the study of electronic configuration of transition metals it is understood that variable oxidation state can be formed as there are both ns and (n-1)d electrons in bonding. The participation of ns electrons in bonding leads to +2 oxidation state which is a lower oxidation state. The ..

The basic assumption(s) for estimating the difference between two variances is/are: I. The samples must be dependent on each other. II. The samples must be independent of each other. III. The populations from which the samples were obtained must be normally distributed. IV. The ..

ax + b = 0 is a linear equation in one variable. Consider the equation 2x + 4 = 0 2x = -4 x = -2 Since this equation is independent of y, for all values of y, x = -2 Hence x = -2 is a line parallel to the y-axis at x = -2. Consider the equation y - 5 = 0 y - 5 = 0 y = 5 Since th..

State whether true or false: "Two uncorrelated variables may not be independent.". Choose the correct statement for the data given in the table. x - 4 - 2 0 2 4 y 256 16 0 16 256 => false; two uncorrelated variables are always independent or true; two uncorre..

Select the requirements of a binomial probability experiment. I. There must be fixed number of trials. II. Each trial can have only two outcomes, or outcomes that can be reduced to two outcomes. III. The outcomes of each trial must be dependent on each other. IV. The outcomes of each tria..

The formula for the adjusted R 2 using n the number of datasets and k the number of independent variables is => R 2 adj = 1 - [ ( 1 - R 2 ) ( n - 1 ) n - k - 1 ] or R 2 adj = 1 - [ R 2 ( n - 1 ) n - k - 1 ] or R 2 adj = 1 - [ R 2 ( n - k - 1 ) n - 1 ] or R 2 adj = 1 - [ ( 1 - R ..
