To help you understand the difference between statistical and non-statistical questions, let’s start with definitions:
- **Statistical questions** are those that anticipate variability in the data and can be answered by collecting data from a group. They often ask about the characteristics or behaviors of a population.
- **Non-statistical questions** seek specific facts or a single piece of information that does not involve variance or do not require data collection from a group.
### Statistical and Non-Statistical Questions
#### Statistical Question:
- **What are the average number of text messages sent by teenagers each day?**
- *Explanation: This question anticipates variability as different teenagers send different amounts of text messages, and it requires data collection from a population of teenagers to determine an average.*
#### Non-Statistical Question:
- **How many text messages do you send yourself each day?**
- *Explanation: This question seeks a specific answer from an individual and does not involve variability among different individuals. It does not require data collection from a group.*
### Additional Example Questions Related to Teenagers and Text Messaging:
1. **Statistical Question:**
- **What percentage of teenagers prefer texting over calling?**
- *Explanation: This question anticipates different preferences among teenagers and would require data collected from a group of teenagers to measure their preferences.*
2. **Non-Statistical Question:**
- **Do you prefer texting or calling?**
- *Explanation: This question seeks an individual’s opinion and does not involve variability or require a broader data collection.*
### Evaluation of Provided Questions:
1. **Political Group Question:** *(Who are the 2 major candidates running for president this year?)*
- **Non-Statistical:** This question seeks specific information with no variability in answers as it asks for known candidates.
2. **Journalism Club Question:** *(About how much time do you spend reading each day?)*
- **Statistical:** This question anticipates a range of answers and variability as it collects data from multiple students.
3. **Movie Theatre Question:** *(Did you enjoy the movie?)*
- **Statistical:** This question anticipates variability as different individuals may have different opinions about the movie.
4. **Guidance Counselor Question:** *(How many clubs and sports are open to sixth graders at this school?)*
- **Non-Statistical:** This question seeks a specific fact which does not involve variability.
5. **Sixth Grader Question:** *(How many clubs and sports are open to sixth graders at this school?)*
- **Non-Statistical:** Similar to the previous, it seeks a specific factual answer with no variability.
By carefully considering the phrasing of each question, one can determine whether it is statistical or non-statistical based on the need for data collection and the anticipation of variability in the responses.
