#### Transcript Recognize statistical questions.

Learning Objective We will recognize1 statistical questions. CFU What are we going to do? What does recognize mean? Recognize means __________. Activate Prior Knowledge Determine the difference between the two question types. Type A Type B “How many hours a week does Jose spend on math homework?” “How many hours a week do my classmates spend on math homework?” “What is the distance from my house to school?” “How far do my classmates travel from home to school?” “How much does my backpack weigh?” “How much does each student’s backpack weigh at my school?” Make Connection Students, some questions only have one answer and others have multiple answers. Questions that have multiple answers are good for exploring real-life problems. Now, we will recognize statistical questions.

For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question because one anticipates variability in students’ ages. Lesson to be used by EDI-trained teachers only. Concept Development A statistical question expects variability2 in the data3 collected. • A statistical question is a question that can be investigated4 by collecting a set of data. Statistical Question Javier spent 6 hours on math homework last week. He wants to investigate how much time the students in his classroom spend doing math homework. Data Set “How many hours a week do my classmates spend on math homework?” The statistical question can be answered by collecting data on how many hours students spend on math homework in a week. Variability in the data collected can be expected because some students may finish homework faster than others.

Skill Development/Guided Practice A statistical question expects variability in the data collected. • A statistical question is a question that can be investigated by collecting a set of data. CFU Recognize statistical questions. 1 Read the situation carefully. 2 Write a statistical question for the situation, if necessary. 3 Describe how data can be collected. 4 Explain variability in the data that can be expected. 1. Verla would like to gather information on the number of computers her classmates have at home. 2. Karl is interested in studying the exercise habits of people in his city. Statistical Question: “How many computers do my classmates have at home?” Statistical Question: “How often do people in my city exercise?” 2 How did I/you write a statistical question? 3 How did I/you describe how data can be collected? 4 How did I/you explain any variability in the data?
