Q1 – In SPSS, if you specify a column as the data type 'string', what will the column accept?
- Only numbers to be entered
- Only letters to be entered
- Any type of user entry (letters and numbers) (correct)
- SPSS will delete that column as an error has been made
Q2 – What is required when entering data from a repeated measures design with two conditions in SPSS?
Q2 – What is required when entering data from a repeated measures design with two conditions in SPSS?
- The first column needs to be coded into the two conditions (correct)
- The first column needs to have participants' names
- The data for the two conditions needs to be entered in two adjacent columns
- Data from repeated measures designs cannot be entered into SPSS

Study Notes
SPSS Data Types and Design Requirements
- A column specified as 'string' in SPSS accepts alphanumeric characters, including letters, numbers, and special characters.
Data Entry Requirements for Different Designs
- When entering data from a repeated measures design with two conditions in SPSS, each participant's data should be entered on a separate row, with multiple columns representing the different conditions.
- When entering data from an independent samples design with two conditions in SPSS, each group's data should be entered in separate rows, with a separate column indicating the group membership (e.g., 0 and 1).
Impact of Data Type on Data Entry
- If a column is specified as 'string' in SPSS and only numbers are entered, the numbers will be treated as strings, not as numerical values.
Coding in Repeated Measures Design
- Coding the first column in a repeated measures design in SPSS allows for identification of the participants and linking of their data across different conditions.
