Question
1) I want you to survey 18 people (all 18 years old or older). 2) Ask all 18 people the SAME TWO QUESTIONS. Your questions
1) I want you to survey 18 people (all 18 years old or older).
2) Ask all 18 people the SAME TWO QUESTIONS. Your questions can be about anything as long as you are using a numerical number on an interval or ratio scale of measurement.
***For example: Is there a correlation between the number of cups of coffee people drink (question #1) and the number of hours they sleep(question #2)? You would ask 18 people BOTH questions. Record the numbers on the next page. Now you cant use that research topic! Try to pick questions that ACTUALLY interest you to see if some kind of relationship exists between those variables.
3) Once you have your 18 responses from participants for both questions, calculate the following answers in your HANDWRITING. ***ROUND ALL DECIMALS TO 2 DECIMAL PLACES WHENEVER AND WHEREVER THE DECIMALS OCCUR***
QUESTION1:_______________________________________________________QUESTION2:_______________________________________________________1. Using YOUR data, list out all of your scores and completethe table.X Y X Y XY
.
2.Calculate Pearsons r using the given formula. Make sure you show all of your work and round to 2 decimal places whenever and wherever the decimal occurs
3. What is the null hypothesis? ***hint: this is STANDARD for all research studies!***
4. How manydegrees of freedom do you have?N-2 =
5. Using the Table of Minimum Values for the Pearson Correlation and the .05 level of significance, what is the critical value for your project? 6. Is your observed (calculated) value of Pearson r statistically significant or statistically not significant? WHY? 7. Did you reject or fail to reject the null hypothesis?
8. Using your observed (calculated) value or Pearson r, what is the value of the coefficient of determination?r2
you decided the data its just survey so just put 18 number for x and 18 for y I don't have the data
