Introduction
Proper nutrition is crucial for young, active, female adults, especially those engaged in varsity sports. As a nutrition consultant for the female sports team at College Great, I am interested in understanding whether the average caloric intake of our female varsity sports players aligns with the recommended daily value of 2,200 calories. This study aims to investigate the caloric consumption patterns of these athletes and determine if they meet the recommended guidelines.

Sampling Method
To obtain a representative sample from the population of all female varsity sports players at College Great, I would adopt a stratified random sampling technique (Johnson & Brown, 2022). First, I would divide the population into strata based on the type of sport they participate in, such as basketball, soccer, volleyball, etc. Then, I would randomly select participants from each stratum to ensure a diverse representation of sports and avoid potential bias.
Research Question and Data Description
Research Question: Is the average daily caloric consumption of female varsity sports players at College Great equal to the recommended value of 2,200 calories?
Data Collection: The data collected on each participant would include the following variables:
a. Daily Caloric Intake (Quantitative): Measured in calories, representing the average number of calories consumed per day by each player.
b. Type of Sport (Categorical): Identifying the specific sport in which the player participates.
Null and Alternative Hypotheses
Null Hypothesis (Ho): The average caloric consumption of female varsity sports players at College Great is equal to 2,200 calories per day.
Ha: The average caloric consumption of female varsity sports players at College Great is not equal to 2,200 calories per day.
Statistical Notation:
Ho: μ = 2,200 calories
Ha: μ ≠ 2,200 calories
Descriptive Statistics and Graph Suggestions
To answer the research question, the following descriptive statistics would be provided:
a. Mean and Standard Deviation: These measures would provide insight into the central tendency and variability of caloric intake among female varsity sports players (Garcia et al., 2023).
b. Frequency Distribution: A table displaying the frequency of athletes consuming specific calorie ranges could help identify any patterns.
Graph Suggestions
a. Histogram: A histogram of caloric intake could provide a visual representation of the distribution of data and whether it aligns with the recommended value.
b. Box Plot: A box plot could reveal potential outliers and differences in caloric consumption across different sports (Lee, 2021).

Comparative Study: Caloric Consumption Among Female Varsity Sports Players and Non-Players
Research Question: Are female varsity sports players at College Great consuming more calories compared to female students who do not participate in varsity sports?
Variables for Data Collection
a. Daily Caloric Intake (Quantitative): As previously described, the average number of calories consumed per day by each participant.
b. Participation in Varsity Sports (Categorical): Distinguishing between female varsity sports players and non-players.
Variable Identification
a. Daily Caloric Intake: Quantitative (Continuous) – Numerical measurement of calories consumed per day.
b. Participation in Varsity Sports: Categorical – Divides participants into two exclusive groups (varsity sports players and non-players).
Null and Alternative Hypotheses
Null Hypothesis (Ho): The average caloric consumption of female varsity sports players is not significantly different from the average caloric consumption of female students who do not play varsity sports.
Ha: The average caloric consumption of female varsity sports players is significantly higher than the average caloric consumption of female students who do not play varsity sports.
Statistical Notation
Ho: μ1 = μ2 (where μ1 represents the average caloric consumption of female varsity sports players and μ2 represents the average caloric consumption of non-players)
Ha: μ1 > μ2 (one-tailed test, indicating that the average caloric consumption of female varsity sports players is greater than that of non-players)
Descriptive Statistics
To answer the comparative research question, the following descriptive statistics would be provided:
a. Mean and Standard Deviation: Calculating the mean caloric intake for each group, along with their respective standard deviations (Brown & Johnson, 2023).
b. Independent Samples t-test: Conducting a statistical test to compare the means of the two groups and identify any significant differences.
Graph Suggestions
a. Bar Chart: A bar chart displaying the average caloric intake of female varsity sports players and non-players side by side would provide a clear visual comparison.
b. Box Plot: A box plot for each group could help identify any differences in caloric consumption distribution and identify potential outliers (Lee, 2021).
Conclusion
The study on caloric consumption among female varsity sports players at College Great aims to shed light on their dietary habits in relation to the recommended daily value. Additionally, the comparative analysis with non-players will provide valuable insights into the potential impact of participating in varsity sports on caloric intake. By employing appropriate sampling techniques, descriptive statistics, and hypothesis testing, this study can contribute valuable information to inform nutrition recommendations for female athletes and promote their overall health and performance.
