Suppose Mrs. Theresa conducted research and tested 10 of her special education students to find the effect of using iPad and notebooks in taking notes on their ability to comprehend and retain science vocabularies in describing the parts of a tomato plant. That means she wanted to find out which method of note-taking (using Ipad or notebook, the manipulative/ independent variables) is significantly beneficial for learning the vocabularies. For this purpose she gave a pre-test before the procedure and then a post-test after the procedure. The results are shown in the table below. Q#1. Name the type of Quantitative Research Mrs. Theresa conducted. Why (reasons) do you think you identified (named) it so? .Q#1. Name the type of Quantitative Research Mrs. Theresa conducted.

Q#1. Name the type of Quantitative Research Mrs. Theresa conducted. Why (reasons) do you think you identified (named) it so?

Q#2. Explain the logic for the type of hypothesis testing to use in estimating population parameters for dependent sample means.

Q#3. Select valid inferential statistics with the reason for dependent sample means.

Q#4. Infer when a t-statistic is used for hypothesis testing for dependent means.

Q#5. Conduct the t-test (work-out the problem) outlining the main assumptions using five steps of hypothesis testingin estimating population parameters from pre-and post-test data obtained from the same sample in this research.

Q#6. Sketch the distributions for answers to the assignment problem for the t-test for dependent means.
