What You Will Submit For Task 1 Frequency Table And Bar Chart For The

Compile a frequency table and a bar chart for the variable “CORRECT” using data from the Caffeine study. The data involves 30 subjects split into two groups: 15 given caffeine (experimental group) and 15 given a placebo (control group). Enter the data into SPSS with two variables: “CAFFEINE” (nominal, with values 1 = Caffeine, 2 = Placebo) and “CORRECT” (scale, representing the number of correct answers on a recall test). Generate a frequency table and bar chart for “CORRECT”, ensuring the display includes frequency counts. Export the output into a Word document for submission.

Paper For Above instruction

The objective of this assignment is to analyze the data from a caffeine and memory recall study conducted with 30 participants, divided evenly into experimental and control groups. The first task involves creating a frequency table and bar chart for the variable “CORRECT,” which represents the number of correct answers on the memory test. This process enables visualization of the distribution of correct answers across the sample and provides foundational descriptive statistics necessary for further analysis.

To begin, all data analysis should be performed in SPSS. The dataset comprises two variables: “CAFFEINE” and “CORRECT.” The “CAFFEINE” variable is nominal, coded with 1 for caffeine and 2 for the placebo, while “CORRECT” is a scale measure indicating the number of questions recalled correctly, with possible values ranging from 0 to 10. Proper data entry involves assigning variable labels and measure types in SPSS: “Caffeine” and “Correct Answers,” with “Caffeine” specified as nominal and “Correct” as scale.

Once the data are entered, the next step is to generate a frequency table and bar chart for “CORRECT.” In SPSS, navigate to “Analyze,” select “Descriptive Statistics,” and choose “Frequencies.” Move “CORRECT” into the analysis variables box, ensure that the “Display frequency tables” box is checked, and then click “Charts.” Select “Bar charts” and ensure “Frequencies” is chosen for the chart values. Click “Continue” and then “OK” to produce the output. The resulting frequency table will show counts for each number of correct answers, while the bar chart visually represents these counts. You should export this output to a Word document for submission, utilizing the “Export” function in SPSS for ease of manipulation and presentation.

This initial descriptive analysis provides insight into the distribution of recall scores among participants, which is vital before conducting further statistical tests. Visualizations like bar charts aid in quickly understanding patterns within the data, such as skewness or modality, while frequency tables provide detailed counts. This step sets the foundation for subsequent statistical measures and graphical representations outlined in later tasks.
