The correct answer is Systematic observation
Systematic observation is a method used to understand how a particular activity or task works. The researcher observes the steps of a process, the tools used, the difficulties that appear, the conversations and results of the work.
Systematic Observation is guided by a defined objective, something you want to know about that activity. The observation is made repeatedly until there is sufficient evidence to state this.
Systematic Observation can be used to do Behavioral Mapping, Task Analysis or Activity Analysis.
Answer: Option 1. is correct
Explanation:
From the given options, <em>Past performance</em> is a variable that doesn't influences chances.
The mere notion that drives this analysis is that circumstances are controlled by an equilibrium between variables that control change and several other which tend to resist change. In order for the change to take place, the variables must be bolstered or on the other hand the resisting variables should be weakened.
The correct answer is option A. 1,18.
Linear regression is a method used to identify the trend Or similarity between two sets of data. All the given points of the data set are plotted and a straight line is drawn with the points. The line is called a line of regression.
F Test is a test that is used to check if the given line of regression is a good fit for the given data set or not. F ratio is the ratio obtained by dividing the two mean square values of the data set.
The numerator of the given regression is always 1
The denominator of the regression is given by n-2=20-2=18.

60. An analysis of regression is used to test the significance of a linear regression equation based on a sample of n=20 individuals. What are the df values for the F-ratio?
a. 1, 18
b. 1, 19
c. 2, 18
d. 2, 19
Answer:
B
Explanation:
The system is contained in a constant-volume container and thermally and mechanically isolated from its surroundings. In this state, the state of equilibrium, both the reactants and the product are in a concentration which have no tendency to change with time.
