The program has received a grant from the State to implement a new training program. The primary goal of the training program is to improve clients work skills so that they can move from a sheltered work environment to a job in a community setting. A requirement of the grant is to submit a 6-month progress report that assesses the effectiveness of the intervention in improving clients work skills. The first 40 clients who qualify for services through the grant are enrolled in the training program. In order to measure clients work skills, a staff member will ask the client to complete a series of tasks that are common in many community job settings that employ adults with Developmental Disabilities (e.g. bagging groceries, washing dishes, etc). Each task will receive a score and these scores will be summed to generate an overall assessment of client work skills. The scores can range from 0 (very poor work skills) to 40 (excellent work skills). Each client is assessed before and after the intervention. There are 3 overall steps to generating the t test output in SPSS: Step 1: Creating the Variables Step 2: Entering the Data Step 3: Running the Dependent t Test (AKA Paired Samples t test) Step 1: Creating the Variables  Directions for creating the Participant ID variable: Open SPSS program, when the SPSS for Windows dialog box appears, click cancel. On bottom of screen, youll see two tabs, data view and variable view. Click on variable view In the Name field, type in the variable name: Participant.ID Use the tab button or the mouse to move the cursor to the Label field. In the Label field, type: Participant ID Number. Use the tab button or the mouse to move the cursor to the Measure field. In the Measure field, change the level of measurement to nominal. Directions for creating the Pre-Test Work Skills variable: In the Name field, type: Pre.test In the Label field, type: Pre-test work skills score The default setting for the Measure field is scale and since the pre-test is a continuous measure, we will leave it as scale. Directions for creating the Post-Test Work Skills variable: In the Name field, type: Post.test In the Label field, type: Post-test work skills score The default setting for the Measure field is scale and since the post-test is a continuous measure, we will leave it as scale. Step 2: Entering the data Click on Data View and enter the following data Participant ID Pre-Test Work Skills ScorePost-Test Work Skills Score1101526839941016512196152972530891791110101516112031129161312191461215810161020171116181424191629208172122272221252318152488256826151527142328121929141730172131683210733918341315351414361719371216381926391119401520 Step 3: Running the Dependent (AKA paired samples) t Test From the top drop down menu, choose Analyze Choose Compare Means Choose Paired Samples T Test In the Paired Samples T Test dialog box, choose Pre-test Work Skills Score Then, choose Post-test Work Skills Score Click on the arrow to send both variables into the box Click OK Using an 8-Step Process for Hypothesis Testing Once you have your output, use the 8-step process for hypothesis testing to describe and interpret your findings. Please refer to the research scenario and your SPSS output to answer the questions. Identify the independent variable and level of measurement Identify the dependent variable and level of measurement State the null hypothesis State the alternative hypothesis Identify the appropriate statistical test, and alpha level Present table of results (SPSS Output)    Describe results and decision to accept or reject the null hypothesis Report THREE things when describing results of the t test 2. t statistic 3. Degrees of freedom 4. p value Provide a discussion of these results. Include: A statement about statistical significance of results A summary of the direction of the relationship between the independent and dependent variables A statement about the meaning of these results A statement about the limitations of the study A statement about the implications of these results for social work practice, policy and/or research.
