Data Analysis and Comparison

Compare the mass of Double Stuff and regular Oreos using statistical measures like standard deviation (SD) and standard error of the mean (SEM) for accuracy․

4․1 Comparing the Mass of Double Stuff and Regular Oreos

To determine if Double Stuff Oreos are truly double stuffed, compare their mass with regular Oreos․ Measure the total mass of whole cookies using a digital scale․

Separate the cookies into wafers and cream, weighing each component․ Double Stuff Oreos averaged 26g of filling, while regular Oreos had 12g, confirming they are double stuffed․ Use statistical tools like mean, SD, and SEM to analyze data accuracy, ensuring reliable results․ This comparison helps students understand precision and variability in scientific measurements, making the experiment both educational and engaging for STEM learning․ The data supports the hypothesis that Double Stuff Oreos contain twice the filling of regular Oreos․

4․2 Statistical Analysis: Using SD and SEM for Accuracy

Statistical analysis enhances the reliability of the experiment by assessing data variability․ Calculate the standard deviation (SD) to measure data spread and the standard error of the mean (SEM) to evaluate sampling error․ These metrics help determine if the difference in filling between Double Stuff and regular Oreos is statistically significant․ For example, if Double Stuff Oreos have a mean filling of 26g (SD=0․5) and regular Oreos 12g (SD=0․3), the SEM will indicate if the observed difference is consistent across samples․ This approach ensures precise and credible conclusions, reinforcing the scientific validity of the experiment․
