Thirty students who failed the state writing exam were placed in a class in which they received additional tutoring. After completing the class, all 30 students retook the exam and earned higher scores. Their success was attributed to the effectiveness of class curriculum. Which source of internal invalidity has not been considered

Answers

Answer 1

The source of internal invalidity that has not been considered is "Statistical Regression."

This is because statistical regression as a source of internal invalidity suggests that when the initial study reveals a huge or low extent of the dependent variable, any change tends to show a different result, affecting the study conclusion.

In this case, the researcher can't be definite about the effectiveness of the class curriculum since all the thirty students that failed initially passed the second time.

Hence, in this case, it is concluded that the correct answer is Statistical regression.

in mexico how do rural celebrations differ from celebrations in big cities

Answers

In Mexico, rural celebrations differ from celebrations in big cities in many ways. The major difference is that "rural celebration is more serious and spiritual while in big cities celebration is more profane and secular.

This is based on the socio-geographical nature of both regions. The rural area of Mexico is more homogenous with people who are conservatives in attitudes.

On the other hand, the big cities of Mexico have many migrants and are more exposed people. Thus, they have secular attitudes and tend not to be religious in their approach to festival celebrations.

Hence, in this case, it is concluded that rural celebration in Mexico is thoughtful while cities celebration is nonreligious.

identify the people in each scenario as occupying either a similar or different social status, according to max weber.

Answers

Max Weber developed a social status system that classifies individuals into different categories.

Max Weber (1864-1920) was a German sociologist who stood out for the theoretical contributions that led him to be listed as one of the fathers of modern sociology.

One of his most prominent studies was the theory of three components of stratification that were:

Class.Status.Power.

These three categories contemplate a multidimensional approach to social stratification that reflects the interaction between:

Wealth.Prestige.Power.

These dimensions refer to the different forms of power. For example:

1. A person who has wealth has the economic power to do what he wants;

2. a person with prestige has social relationships that allow him to do what he wants;

3. a person with power, whether public or private, influences to decide on others without being affected.
