## Step-by-Step Solution ### **Step 1: Understanding the Task** You are asked to use a data sheet (not present in these images) to: - Enter the data into SPSS - Calculate descriptive statistics about your sample (percentages for gender, race, and mean age) Calculate the mean, standard deviation (SD),, and variance behavior scores **Note:** The of tables provided are *z-tables* (areas beneath the normal curve), not the data sheet needed for the calculations. --- ### **Step 2: What You Need to Do** #### **(a) Describe your sample:** - **Percent Males / Females**: (Number of Males or Females / Total Sample) × 100% - **Percent by Ethnicity**: (Number in Group / Total Sample) × 100% - **Mean Age**: Sum of all ages / Number of participants #### **(b) Behavior Scores:** - **Mean**: Sum of behavior scores / Number of scores - **Range**: Max score - Min score - **SD (Standard Deviation)**: \[ SD = \sqrt{\frac{\sum (X_i - \text{Mean})^2}{N-1}} \] - **Variance**: SD squared --- ### **Step 3: Instructions for SPSS** #### **Entering Data** 1. Open SPSS. 2. Enter each participant as a row. 3. Enter variables (columns) such as: Gender, Ethnicity, Age, Behavior Score, etc. 4. Label your variables for clarity. #### **Calculating Descriptives** - **For percentages:** Use the "Frequencies" option for categorical variables. - **For mean, SD, range, variance:** Use "Analyze" → "Descriptive Statistics" → "Descriptives" for the behavior scores. --- ### **Step 4: What to Fill In (Template)** #### **(a) Describe your sample:** | Statistic | Value (Example) | |---------------------------|----------------------| | Percent Males | [Your Calculation]% | | Percent Females | [Your Calculation]% | | Percent Caucasian | [Your Calculation]% | | Percent African American | [Your Calculation]% | | Percent Hispanic | [Your Calculation]% | | Percent Asian American | [Your Calculation]% | | Mean Age | [Your Calculation] | #### **(b) Behavior Scores:** | Statistic | Value (Example) | |------------|--------------------| | Mean | [Your Calculation] | | Range | [Your Calculation] | | SD | [Your Calculation] | | Variance | [Your Calculation] | --- ### **Step 5: Final Answer Example** Since the data sheet is **not provided** in your images, I **cannot fill in the exact numbers**. Here’s what you should do once you have access to the data: 1. **Enter data into SPSS.** 2. **Calculate the above statistics using the instructions.** 3. **Fill in the template with your values.** --- ## **What About the Z-Tables?** The images you attached are z-tables (areas under the normal curve). They are **not needed** for this question unless you are asked to find probabilities or percentiles based on z-scores. --- ## **Summary** - **You need to use the actual sample data sheet** (not shown) to answer the questions. - **Follow the calculation steps above** after entering data into SPSS. - **Fill in the percentages and statistics** in your worksheet as shown in the template. **If you provide the data sheet or sample data, I can walk you through the calculations with actual numbers!**
