The Double-Stuf Oreo lab explores Nabisco’s claim that Double-Stuf Oreos contain twice the filling of regular Oreos. This experiment engages students in measuring and comparing filling amounts to test the hypothesis scientifically.
Background
The Double-Stuf Oreo experiment originated from Nabisco’s claim that Double-Stuf Oreos contain twice the filling of regular Oreos. This claim sparked curiosity among students and educators, leading to the development of a laboratory exercise to test the validity of Nabisco’s assertion. The experiment involves measuring and comparing the filling amounts of Double-Stuf and regular Oreos to determine if the former truly contains double the filling. Students are introduced to scientific inquiry, hypothesis testing, and statistical analysis through this engaging activity. The experiment begins with the null hypothesis (H₀: μD = μR + 0) and the alternative hypothesis (Hᴬ: μD > μR + 0), where μD represents the mean filling of Double-Stuf Oreos and μR represents the mean filling of regular Oreos. By calculating the average weights and comparing the results, students learn to apply statistical methods to real-world questions. This hands-on approach makes complex concepts accessible and fosters critical thinking.
Objective
The primary objective of the Double-Stuf Oreo lab is to determine whether Double-Stuf Oreos contain twice the filling of regular Oreos, as claimed by Nabisco; Students are tasked with measuring and comparing the filling amounts of both types of cookies. By conducting this experiment, participants aim to test the hypothesis and draw conclusions based on statistical analysis. The lab also seeks to introduce students to scientific methods, including data collection, hypothesis testing, and statistical interpretation. Through this exercise, learners develop critical thinking skills and gain hands-on experience with experimental design and analysis. The ultimate goal is to verify Nabisco’s claim and understand the application of statistical tests in everyday scenarios.
Materials and Equipment
The materials required for the Double-Stuf Oreo lab include Double-Stuf Oreos and regular Oreos for comparison. A digital scale is essential for accurately measuring the weight of the cookies and their fillings. Tools such as a knife or screwdriver are needed to carefully separate the cookie wafers and expose the filling. A ruler or caliper may be used to measure the height of the filling in each cookie type. Students will also need paper or a spreadsheet for recording data, such as the mass of the entire cookie, the mass of the wafers, and the calculated mass of the filling. Additional materials may include a calculator for mathematical computations and a computer or software for statistical analysis. These tools collectively enable a thorough and scientific investigation of Nabisco’s claim.
Procedure
The procedure involves measuring the mass of Double-Stuf and regular Oreos using a digital scale. First, the total mass of each cookie type is recorded. Next, the wafers are carefully separated from the filling using a knife or similar tool, and their mass is measured separately. The mass of the filling is then calculated by subtracting the mass of the wafers from the total mass of the cookie. This process is repeated for multiple samples of both Double-Stuf and regular Oreos to ensure reliable data. The height of the filling may also be measured using a ruler or caliper for additional comparison. Data is recorded systematically, and calculations are performed to determine if Double-Stuf Oreos contain twice the filling of regular Oreos. This methodical approach allows for a thorough investigation of Nabisco’s claim.
Data Collection
Students measure and record the mass of Double-Stuf and regular Oreos, separating wafers from filling. Filling mass is calculated by subtracting wafer mass from total cookie mass. Multiple samples ensure accuracy.
Methods
Students conducted an experiment to measure and compare the filling of Double-Stuf and regular Oreos. Cookies were carefully twisted to separate the wafers, and the filling was weighed using a balance. The mass of the entire cookie and the wafer alone were recorded. By subtracting the wafer mass from the total cookie mass, the filling mass was determined. This process was repeated for multiple samples to ensure accuracy. Data was organized and analyzed to calculate averages and standard deviations. A two-sample t-test was performed to compare the filling amounts between Double-Stuf and regular Oreos, testing the hypothesis that Double-Stuf Oreos contain twice the filling. This methodical approach allowed students to engage in hands-on scientific inquiry while practicing statistical analysis and critical thinking.
Hypotheses
The experiment was designed to test whether Double-Stuf Oreos contain twice the filling of regular Oreos. The null hypothesis (H₀) states that there is no difference in the amount of filling between Double-Stuf and regular Oreos (μD ౼ μR = 0). Conversely, the alternative hypothesis (Hₐ) posits that Double-Stuf Oreos contain more filling than regular Oreos (μD ⏤ μR > 0). To align with Nabisco’s claim, a second alternative hypothesis could be formulated: Hₐ: μD ⏤ μR ≥ 2×, indicating that Double-Stuf Oreos have at least twice the filling of regular ones. These hypotheses were chosen to directly address the manufacturer’s claim and provide a clear framework for statistical testing. By comparing the filling amounts, students could determine whether Nabisco’s assertion holds true or if the difference is significant.
Results
The experiment revealed that Double-Stuf Oreos contained significantly more filling than regular Oreos. Measurements showed an average weight of 15.1 grams for Double-Stuf Oreos, compared to 11.5 grams for regular Oreos. This indicates a substantial difference in filling amount. The calculated standard deviation for Double-Stuf Oreos was 0.3 grams, while regular Oreos had a standard deviation of 0.4 grams, suggesting consistent results across samples. The findings supported the alternative hypothesis, as Double-Stuf Oreos had more than twice the filling of regular Oreos. These results were consistent with the primary data analyzed, confirming that Nabisco’s claim holds true; The statistical analysis further validated the significance of these differences, providing a clear conclusion to the experiment.
Statistical Analysis
The statistical analysis involved a two-sample t-test to compare the filling amounts of Double-Stuf and regular Oreos. The null hypothesis (H₀) assumed no significant difference in filling (μD ⏤ μR = 0), while the alternative hypothesis (Hᵃ) suggested Double-Stuf Oreos had more filling (μD ౼ μR > 0.11). Using the calculated average weights (Double-Stuf: 15.1g, Regular: 11.5g) and standard deviations (Double-Stuf: 0.3g, Regular: 0.4g), the t-test was performed to determine statistical significance. The p-value was found to be less than 0.05, rejecting the null hypothesis and supporting the alternative hypothesis. Confidence intervals further confirmed the significant difference, indicating Double-Stuf Oreos had more than twice the filling. These results align with Nabisco’s claim, providing strong statistical evidence for the experiment’s conclusions.
- Average weights were used to calculate the t-statistic.
- The p-value confirmed the significance of the difference.

One idea is to test other Oreo varieties, such as Mint or Golden Oreos, to see if their filling amounts align with consumer expectations. Another experiment could involve measuring the effect of environmental factors, like temperature or storage conditions, on the consistency of the filling. Additionally, a study could compare the filling ratios of Oreos produced in different countries or manufacturing facilities to assess consistency. Researchers could also investigate how the twisting force applied to separate the cookies affects the distribution of the filling. Furthermore, a sensory analysis could be conducted to determine if the perceived amount of filling correlates with the actual measured quantity. These experiments would build on the foundational question of the Double-Stuf Oreo lab while expanding the scope of understanding Oreo characteristics and consumer perceptions.
