The experiment would be established to determine the influence of the drug in reducing children's hyperactivity. With that, we can say that the independent variable would be the drug, and the dependent variable would be the reduction of hyperactivity.

To perform this experiment, a sample of 30 children diagnosed with hyperactivity would be established. These children would be divided into groups containing 3 children. Each group would be composed of children of the same age, but children in one group would be different in age from children in another group.

In each group, two children would receive a recommended dose of medication, while the other child would receive a dose of placebo (they would receive a dose of other material, which is not the medication and has no effect on the body). The child who received the placebo would be the control. Neither children nor parents would know who is receiving the placebo and who is receiving the medication.

The experiment would last for 3 months and it would be necessary for parents to note the changes in their children's hyperactive behaviors, if any.

The evaluation of the result would be done by comparing the notes of the parents in each group of children. It would be noted if there were significant differences between the behavior of the children who received the medication and those who did not, in each group. Then an assessment would be made, which group had the most significant behavioral differences, to assess whether the drug is more efficient at a given age.

Answer:

Part A:

The cofounding variable is a factor that could cause a result on the experiment. This would be the people taking extra food.

Independent variable would be being asked to sign in or not and take free food, because independent variable is a variable that is changed or manipulated and in this case the people were split in half and the hypothesis is that the people who didn't sign in would take more food.

Operational definitions are important when conducting research because it defines all the variables in the experiment, so it can be replicated. The operational def for the dependent variable would be "Doing the right thing even though you aren't being watched"

Part B:

The data does not support the hypothesis because even the people who signed in could've taken extra food when the dean wasn't looking. The findings cannot be generalized to all students because some students could have been taught better and can differentiate between right and wrong. So the people who were not signed in could've just taken one burger and drink, and the people who were signed in might feel obligated to take more than one burger because they had signed in and didn't just come without signing in.

The study is not a naturalistic observation because the observer did not look at the people who took the food and which side took more food.

To overcome difficulties in relationships, both parties must be accommodating. Which of the following behaviors reflect a spirit
pav-90 [236]

Answer:

  • A calm, quiet tone of voice
  • Seeking common ground

Explanation:

The most important aspects that should be considered to avoid the difficulties in a relationship should be, keeping the tone of voice as calm as possible and identifying the common ground.

Lets understand with a famous quote, "It’s not what you say, it’s how you say it." The problem in a relationship starts when we use inappropriate tone to communicate our point to the other person. Often we do not realize how bad our tone is until the other person feels offensive and reacts.  Several studies have proved that how partners discuss their problems and talk about them has a lot of influence on the overall health of relationship. If people speak to each other with respect even when they do not agree at certain point, it is more probable to understand each other's point and wind up things happily.

Similarly, identifying the  areas of common ground is also an important quality of healthy relationship. Once you identify what is that thing, which is a good outcome, both for you and your partner (or any other relationship), you will compromise and respect each other's opinions.

For example: There is an employee who is asking for a leave so that she spends time with his kids. But his boss is concerned that work will be left uncompleted if he is absent for many days. They negotiate and reach the conclusion that employee will work from home on less number of hours.The boss has agreed to trade his onsite presence for the work that is completed and similarly,employee has agreed to trade her extended leave for less number of hours.
