Use this assessment as an opportunity to demonstrate the breadth of your knowledge and understanding of experimental design.Respond to the following question in essay format. Approximately, three to four paragraphs or 500-550 words.

G. has just completed a study that shows a correlation between the amount of time children watch television and their attention spans. Assume the correlation was r = -.34. State an experimental hypothesis based on this finding and devise a simple procedure for testing it.

Expert Solution

Methodology

Objective:

To explore the relationship between the amount of time children watch television and their attention spans.

Hypothesis:

There will be an inverse relationship between the amount of time the children watch television and their attention spans.

Experimental design:

Correlational design

Variables:

1) Amount of time children watch television in hours

2) Attention span

Method:

Signed consent forms from parents are obtained.

Measures:

Amount of time children watch television: The parents will be given instructions to record the amount of time in hours their children watch television each day for a week. The average time taken by each child will be computed.

· Attention span: The attention span of the child will be measured using a tachistocope in silent room without distraction. The child will be given there instructions:

“Listen to me very carefully. This is an instruments that measures your attention span. I will flash you some cards inside this instruments and it will be very quick. Try to focus and pay attention to the number of dots in this card. This will be repeated for a number times. If you have any doubts, please ask. Let us clarify them before we begin"

Statistical Analysis

Pearson r will be calculated to obtain the coefficient of correlation to understand the relationship of two variables.

Results

Results from the study shows that the variables have a weak negative correlation. So, we can conclude that though the correlation is not strong, the amount of time children watch television and their attention span has an inverse relationship. As the number of hours increase, the attention span decreases. This accepts the hypothesis of the study.
