Cohen’s guidelines (which do not apply to all applications) are
that small, medium, and large values of r correspond to
A).46, .67, .84
B).10, .20, .30
C) .00, .50, 1.00
D) .10, .30, .50

Answers

Answer 1

Option D) .10, .30, .50 accurately represents Cohen's guidelines for interpreting the strength of a correlation coefficient.

Cohen's guidelines for interpreting the strength of a correlation coefficient, typically denoted as r, categorize small, medium, and large values based on the magnitude of the correlation. These guidelines help assess the strength and practical significance of the relationship between variables. Let's examine the options provided:

A) .46, .67, .84

B) .10, .20, .30

C) .00, .50, 1.00

D) .10, .30, .50

Among these options, the correct choice is D) .10, .30, .50.

According to Cohen's guidelines, small, medium, and large values of r correspond to approximately:

Small: r = 0.10

Medium: r = 0.30

Large: r = 0.50

Therefore, option D) .10, .30, .50 accurately represents Cohen's guidelines for interpreting the strength of a correlation coefficient.

Answers

If all three models produce straight lines when graphed, they are linear models

Rewrite hypothesis 1 = 0 in terms of the other two models.

Hypothesis 1 in the first model is:B3 = 0.

Hypothesis 1 in the second model is: B2 = 0.

Hypothesis 1 in the third model is: B1 + 2B2 + 3B3 = 0.

All three models are linear in the parameters because each explanatory variable has a coefficient attached to it. Linear regression is the process of fitting a linear equation to a given set of data points.

This equation can be used to predict the value of the dependent variable (Y) based on the value of the independent variable (X).

A linear equation is an equation that produces a straight line when graphed.

Therefore, if all three models produce straight lines when graphed, they are linear models

INSTRUCTIONS: TIME: 2 HOURS CASE (20 Marks) Growing Government Regulations in IRs in Nepall Since 2046 BS (1990) the Nepalese Government has increased its regulation of the way employers treat employees. The Trade Union Act 2074 permits workers to join unions, the Minimum Wages Regulations, guarantees a minimum wage, the Industrial Enterprise Act ensures a safe and healthy environment, the Labour Act 2074 offers compensation to injured workers, the Payment of Wages Clause; checks fraudulent practices in the payment of wages to workers. The regulatory framework covering factories, union-management relations, compensation issues, dispute settlement, etc., is quite rigorous and elaborate. There are laws that prohibit discrimination and restrict the freedom of employers to make HR decisions in other areas as well. As the guardian of the economy and as a regulator of employment relations, the Nepal Government does not seem to loosen its grip in the near future. Experts believe that the trend toward increased governmental intervention will continue. They base their arguments on the current trends in developed countries in this area in the form of employer-sponsored health insurance schemes, greater job security, improved treatment, etc. Others, (especially private entrepreneurs), are not very optimistic about governments trying to regulate the employer-employee relations closely. Competitive pressures, deregulation of industry, rising wage bills, increasing number of older employees needing social security protection, inflationary pressures, heavy taxes and a host of other factors having a significant bearing on the profitability of a firm do not seem to support government's active intervention in industry. These experts contend that if Nepalese firms have to remain competitive in international markets, they should be freed from all types of control, especially those imposed by the government.
