Answer:
Grid analysis is best used when a decision needs to consider multiple outcomes and different criteria. The format of this method however, can provide bias to a certain outcome. The process is only as good as the quality of information placed within the grid including the scoring. Once a factor is graded or placed subjectively, objectivity is compromised in this method. Also, this method keeps decision making strictly in a rational manner. But, it is considered unhealthy to be linear in decision making and one-sided. It is best to base decisions from a rational and take emotions into account as well.
Answer:
This is a multicolinearity problem and the student should determine the variable(s) that cause(s) the problem and remove it.
Explanation:
This information means that there exists a linear combination between the independent variables. The problem might have developed due to multicolinearity producing almost perfectly linearly dependent columns.
This could also be as a results of single matrix created when the student use an incorrect indicator variables and included an additional indicator column which created linearly dependent columns.
It’s hz and bandwidth, 5ghz is better then a 2.5ghz but the wavelength is more condensed so it won’t travel so far so the 5ghz will be faster but the 2.5ghz will go further.
