Data Representation Skills in ACT Science

The video tutorial covers strategies for tackling data representation passages in the ACT science section. It emphasizes skimming passages, focusing on charts and graphs, and using answer choices to guide data location. Examples include analyzing a table on chicken breeds and interpreting a graph on vapor pressure. The tutorial also explores ocean chemistry changes due to CO2 absorption, highlighting the importance of understanding data to answer questions effectively.

What is the primary role of data for a scientist?

• To prove or disprove hypotheses

• To make their work harder

• To fill up research papers

• To confuse their audience

What type of passages does the ACT science section include?

• Philosophical essays

• Charts, graphs, and pictures

• Fictional stories

• Only textual passages

What is the first step in approaching data representation questions?

• Reading the entire passage thoroughly

• Skimming the introduction and going to the questions

• Guessing the answers

• Skipping the questions

What is a recommended strategy when you're unsure of an answer in the ACT science section?

• Ask a friend

• Guess randomly

• Look at the answer choices for clues

• Skip the question

According to the chicken breeds study, what is the relationship between resistance to illness and egg laying?

• Direct relationship

• Inverse relationship

• No direct relationship

• Complicated relationship

In the vapor pressure example, what causes an organic compound to boil at a lower temperature?

• Unequal atmospheric and vapor pressures

• Vapor pressure greater than atmospheric pressure

• Decrease in atmospheric pressure

• Increase in vapor pressure

What should you pay attention to in graphs according to the tutorial?

• Only the colors used

• Legend, headings, and axes

• The size of the graph only

• Graphs are not important

What did the tutorial suggest about boiling points of organic compounds?

• They are constant

• Depend on vapor pressure

• Are irrelevant to temperature

• Only depend on atmospheric pressure

How does atmospheric CO2 concentration affect ocean pH according to Table 2?

• pH increases

• pH decreases

• pH remains constant

• pH fluctuates unpredictably

What happens to bicarbonate levels as CO2 concentration increases in water?

• Remains the same

• Becomes toxic

• Increases

• Decreases
