Joni wants to measure the degree to which male college students belong to the political left (liberal). She decides simply to measure the length of male college students hair using a ruler. Her hypothesis is that longer hair will mean more left-wing (liberal) beliefs. Required:
a. Is this method likely to be reliable? Why?
b. This measurement appears to be invalid. Why?
c. Nevertheless, it is possible that measuring politics by hair length might have some predictive validity. Explain how this could happen.

It is explained below

Step-by-step explanation:

Taking into account the required points we can say the following:

In this case measuring the duration of hair is reliable. The purpose for my opinion is that regardless of how often Joni will degree a persons hair the effects will always be more or less the same. There fore, we are able to rely on the fact that the outcomes may be similar this method is reliable. On the other hand, this technique isn't valid, due to the fact the length of a persons' hair has nothing to do with political opinion. The prediction theory that occurs to me with respect to the model is that the longer the person's hair is, the more they tend to be liberal, due to the rebellious thinking of the left-wing.
