Chloe asked students in her school band these two questions:
Question 1: How many days per week do you practice your instrument?
Question 2: How many times will our band perform this year?
Answer Yes or No to each of the following questions.
Is question 1 a statistical question?
Is question 2 a statistical question?
No for both questions.
How come???,,,,
Question 1 asks for a numerical response and can be analyzed statistically, but it is not a statistical question because it does not ask about a population or sample, and does not imply any statistical inference.
Question 2 does not provide any variability or data to analyze statistically, as it is a closed-ended question with a fixed answer. Therefore, it is not a statistical question.
OHH... okay I guees><<<>>>><<<?
I hope that helps! Let me know if you have any further questions.
What is a statical question><?..
A statistical question is a question that can be answered by collecting and analyzing data. It is a question that can be phrased in a way that allows for variability in the data and for statistical inference to be drawn from the analysis of that data.
A statistical question typically involves at least one of the following elements:
1. A population or sample from which data can be collected
2. A variable of interest that can be measured or observed
3. A level of variation in the data that can be analyzed statistically
Examples of statistical questions include:
- What is the average height of students in this class?
- How many hours per week do people in this city spend exercising?
- Is there a relationship between temperature and ice cream sales?
In general, a good statistical question should be open-ended, with no predetermined answer, and it should allow for a variety of data to be collected and analyzed.
So a statical question can have more than 1 answer?
Yes, a statistical question can have multiple answers due to the variability present in the data. For example, the question "What is the average score of students on a math test?" is a statistical question because it involves a variable of interest (test score), a population or sample (students), and a level of variability in the data.
The answer to this question may not always be the same, as the scores may vary from student to student or from one test administration to another. Depending on the sample size and the distribution of scores, the average could also differ. Therefore, the answer to the question could be any number within a range of possible values.
To determine whether a question is statistical or not, we need to understand the nature of statistical questions.
A statistical question is a question that can be answered by collecting and analyzing data. It involves variability, multiple possible answers, and the possibility of different outcomes.
Let's analyze each question:
Question 1: "How many days per week do you practice your instrument?"
This question asks about the frequency of practicing instruments, and it can have different answers for different individuals. The answers may vary from person to person, and each response could be different. Therefore, this is a statistical question.
Question 2: "How many times will our band perform this year?"
This question asks for a specific number of performances for the band. It does not involve variability or different possible outcomes. The answer will be a single, fixed number. Hence, this is not a statistical question.
To summarize:
Question 1 is a statistical question because it involves variability and multiple possible answers.
Question 2 is not a statistical question because it asks for a specific number without any variability or multiple possible outcomes.
