SPSS quick tips for assessment
Hi,
Please try and follow the following steps for the third assessment. Please do not hesitate to call/chat/Mail me for your queries especially if you are still struggling with the dataset.
First time you click you get a dialog page like this:
Click Dont show this dialog in the future (Lt bottom) and click Close (Rt bottom).
Step 1. Importing the dataset. (How to import the dataset for assessment.)
File>Open>Data
Go to your respective folder where you have the file.
By default the file is an SPSS file (.sav) thatll open once you select it. [Remember to look in your computer drive in the Open Data box- Documents: Scroll Z drive your computer].
Step 2. Managing the variable view
Unlike Excel, SPSS has a data view and a variable view. Click Data and Variable view to appreciate this.
The variable view must be corrected & detailed before analysis.
The most important correction is coding or attaching value labels such as in Exposure, 0 stands for control group and 1 for experimental group, Similarly for outcome, location and gender. (Is this already done for your dataset- look in values)
The other important correction is measure or type of variable. All the variables are nominal except ID and last variable. The ID is scale variable (continuous) and the last variable is an ordinal variable.
Step 3. Analyzing the data
If you have the correct dataset with you, proceed with the analysis.
Task- 1 Describe and graphically present all data using descriptive statistical methods including prevalence and incidence (e.g., descriptive frequencies). (equivalent to 250 words)
Answer:
1. Go to Analyze>Descriptive statistics>Frequencies>Select all the variables on the left except ID
2. On the right click Charts (2nd from top). In charts subdialog select either Bar chart or Pie Chart as per your preference. Select OK in subdialog of Charts.
3. Select OK in Frequencies dialog box.
4. You have your output. Save it. Go to File (Top Left) and Save As: Name it Task 1_TomHanks (change if your name isnt Tom Hanks ). You need to submit the output files as well.
(Just the prevalence of STI, and other f=demographic descriptors)
Task 2. Calculate relationships between variables to answer the scenario question (e.g., correlation, t-test, chi-square/crosstab, ANOVA you will need to decide which variables to use, the most appropriate tests and why). (equivalent to 500 words)
RQ: whether receiving relationships and sexuality education (RSE) in school has positive impacts on sexual health?
1. Go to Analyze>Descriptive statistics>Crosstabs
2. In the Row RSE, Column Diagnosed ever
3. Click Statistics on second right- choose Chi square> Continue
4. Click Cells on third right- choose percentage > rows
5. Click Display Clustered bar charts at the bottom
5. Click OK
6. Save output file as Task 2_TomHanks
You do not necessarily need a graphical presentation here, the table suffices along with statistical results table. Always better to show this graph though.
