A group of 6th-grade students are studying where water is located on the Earth’s surface. The graph shows the distribution of water on Earth's surface.  Which questions can students MOST LIKELY ask to determine where water is located on the Earth’s surface?

• Is most of the Earth’s freshwater found in the oceans?

• Is most of the Earth’s freshwater found in groundwater?

• Is most of the Earth’s global water available in the oceans?

• Is most of the Earth’s global water available on the surface?

Which of the following BEST predicts the outcome of the experiment and explains why?

• The beginning amount of water in the container would be less than the ending amount of water in the container because the water evaporated decreasing the water level.

• The beginning amount of water in the container would be more than the ending amount of water in the container because the process of condensation increases the water level.

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated increased the water level but then came back as precipitation which decreased the water level again.

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated decreased the water level but then came back as precipitation which increased the water level again.

What does CFA stand for in the context of scientific data analysis?

• Common Factor Analysis

• Confirmatory Factor Analysis

• Cumulative Frequency Analysis

• Causal Factor Analysis

In Confirmatory Factor Analysis (CFA), what is the primary purpose of the model?

• To explore potential underlying factor structures

• To confirm a hypothesized factor structure

• To visualize data distributions

• To calculate mean and standard deviation

Which of the following is a key assumption in Confirmatory Factor Analysis?

• Variables are normally distributed

• Variables are independent

• Variables are categorical

• Variables are binary

In CFA, what is the role of a 'factor loading'?

• It measures the correlation between observed variables

• It represents the variance explained by a factor

• It indicates the reliability of a factor

• It shows the mean difference between groups
