A test contracting firm has agreed to create a three part social studies test intended to measure sixth graders knowledge of geo

graphy, government, and history. The test is to be used as a statewide assessment to govern the allocation of staff development funds for elementary teachers. Because of the limitations in administrative time, only 15 items are allowed for each of the three content areas. If the test development firm wants to know if its three test subsections are measuring, with suitable consistency, what they are supposed to be measuring, what kind of reliability evidence would be best?

Explanation:

In discipline such as research and statistics, internal consistency is referred to as or known as typically or usually a measure that is based on correlations in between different variable and items particularly on a same test or maybe on sub-scale on the larger test.

A Pearson’s correlation coefficient of –.5 would be represented by a scatterplot in which:
Margarita [4]

Answer:

A. There is a moderately good fit between the regression line and the individual data points on the scatterplot.

Explanation:

A -.5 correlation coefficient indicates a moderate negative correlation, which means that as the x variable increases in value, the y value decreases in value, but only in around half of the situations.

In a scatter plot, this will look like a small cloud of data points that fit more or less well around the regression line. The regression line slopes downward because the variables are inversely proportional (hence the negative coefficient).

c. Unions in developed nations often oppose imports from low-wage countries and advocate trade barriers to protect jobs from wha
liubo4ka [24]

Answer:

The correct answer is II. This argument is in the best interests of the people they represent.

Explanation:

Trade unions in developed countries tend to support trade restrictions, because products made in countries with lower wages are generally cheaper than those made in those developed countries. For example, a pan loaf that costs about 3 dollars in the United States, can cost about 0.75 dollars in Mexico. Therefore, import value, including tariffs, is less than that of national production. This means that, if barriers to trade are not established, many workers lose their jobs due to the fact that national production is terminated due to the possibility of importing said products.

An investigator wanted to know whether chronic lymphocytic leukemia (CLL) had a genetic or environmental etiology. He knew that
dmitriy555 [2]

Answer:

The cause may be environmental

Explanation:

The ratios show that ratio of incidence of chronic lymphocytic leukemia (CLL) in the population of country X is five times higher than the ratio in U.S. whites. However, the ratio of CLL in migrants from Country X to the U. S. is exactly the same as the ratio in U.S. whites. This relationship indicates that, rather than being genetic, the cause of CLL is more likely to be environmental.
