Research Scenario: Does distraction or amount of details affect the ability of people to make good decisions?
In this fictitious scenario, researchers used a mixed design. Thirty participants were split into two groups – No Distraction or Distraction (n=15 per group). All participants were given TWO scenarios based on amount of details (4 or 12), and were asked to make an objective decision at the end of each scenario. Objective decision was the dependent variable and was quantified numerically using an interval scale of measurement.
Assume the data is parametric. Select and conduct the most appropriate statistical test to determine whether distraction or amount of details affect people’s ability to make good decisions.
Let level of significance = 0.05.

To test the distraction affect people’s ability to make good decisions, Calculated F= 35.2851, P=0.0000 which is greater level of significance 0.05 level. We conclude that distraction affect people’s ability to make good decisions.
To test the amount of details affect people’s ability to make good decisions, Calculated F= 64.1963, P=0.0000 which is greater level of significance 0.05 level. We conclude that amount of details affect people’s ability to make good decisions.
To test the interaction between distraction and amount of details , Calculated F= 1324.9978, P=0.0000 which is greater level of significance 0.05 level. We conclude that interaction is significant.
<h2>1.</h2>
So remember that with more than one pair of parentheses, you have to start from the inside and make your way outside.
Firstly, on the left side, solve 5+2 and on the right side solve 4 × 3:
Next, on the left side, solve 3 × 7 and on the right side solve the subtraction:
Lastly, solve the remaining multiplication on the left side and the answer is
<u>Since 84 is not equal to 83, the correct answer is the second option.</u>
<h2>2.</h2>For this, plug 5 into the z variable to solve.
<u>Since 15 = 15 is true, your answer is the first option.</u>
<h2>3.</h2>So for this, it's a similar process as Question 2 except that you are plugging in 0 into the x variable to solve:
<u>Since 8 = 0 is a false statement, the correct answer is the second option.</u>
