Drawing Inferences from Data

What is the main focus of this lesson?

• Studying the history of biology

• Understanding the biology curriculum

• Learning to draw inferences using a dot plot

• Learning about different types of graphs

In a dot plot, what does each dot represent?

• A subject

• A single student

• A group of students

• A class period

What is a common mistake when making inferences from data?

• Using data from multiple sources

• Ignoring the data completely

• Considering all aspects of the data

• Basing inferences on a single aspect of the data

How many students in period 2 studied between 5 and 8 hours?

• 10 students

• 16 students

• 20 students

• 25 students

What is the median study time for period 1?

• 6 hours

• 5 hours

• 4 hours

• 3 hours

What is the estimated mean study time for period 2?

• 6 hours

• 4 hours

• 3 hours

• 5 hours

Which period is more likely to ace the biology final?

• Both periods equally

• Period 2

• Neither period

• Period 1

What is an inference?

• A fact that needs no evidence

• A random assumption

• A statement based on observation and prior knowledge

• A guess without any basis

Why is it important to make multiple observations?

• To ensure the inference is well-informed

• To make the process longer

• To avoid making any inference

• To confuse the data

What does the lesson emphasize about drawing inferences?

• Inferences are not necessary

• Inferences should be based on a single observation

• Inferences should be drawn without any data

• Inferences should be based on multiple observations
