Follow PHANTOMS acronym ### Investigating the Time to Attain a Bachelor's Degree: Community College Transfer Students### Research QuestionDoes the evidence suggest that community college transfer students take **longer** to attain a bachelor’s degree? Use a significance level of 0.01.### Methodology: Structured Approach Guide#### P - Parameter StatementDefine the population parameters involved in the study.#### H - HypothesesConstruct the null hypothesis (H₀) and the alternative hypothesis (H₁) for the research question.#### A - Assumptions & ConditionsIdentify and validate the assumptions and conditions that must be met for the statistical tests being used.#### N - Name the TestSpecify the statistical test that will be conducted to examine the hypotheses.#### T - Test StatisticCalculate the test statistic that allows you to determine the relationship between the data and the hypotheses.#### O - Obtain the P-ValueObtain the p-value associated with the test statistic. This p-value helps in making a decision regarding the null hypothesis.#### M - Make a Decision about the Null HypothesisBased on the p-value and the significance level, make a decision to either reject or not reject the null hypothesis.#### S - State Your Conclusion About the ClaimClearly state the conclusion about the claim concerning the time required for community college transfer students to attain a bachelor’s degree.---This structured approach will guide your analysis and ensure a comprehensive examination of whether community college transfer students take longer to complete their bachelor's degrees compared to non-transfer students, adhering to the significance level of 0.01. **Educational Research Analysis: Time to Graduate for Community College and 4-Year Institution Students**Clifford Adelman, a researcher with the Department of Education, conducted a longitudinal study on a cohort of students who graduated from high school in 1992.

Power Operation

Power operation is topic of algebra in Math. It is use to represent repeated multiplication. Very big number and very small number can be easily express using power operation. Power operation is useful in many fields. In space engineering, it helps in representing the distance or size of particular heavenly body. In medical field, it is used to represent very small size. In medical field it helps to mention size of bacteria or virus.

Exponents

The exponent or power or index of a variable/number is the number of times that variable/number is multiplied by itself.

**Educational Research Analysis: Time to Graduate for Community College and 4-Year Institution Students**

Clifford Adelman, a researcher with the Department of Education, conducted a longitudinal study on a cohort of students who graduated from high school in 1992. His research aimed to monitor the progress of these students towards completing a bachelor's degree. A key focus of this study was to examine whether students who began their higher education at a community college took longer to earn a bachelor's degree compared to those who immediately enrolled and stayed at a 4-year institution.

**Research Findings Summary:**

| | Community College | 4-Year Institution |
|-------------------------|-------------------|-------------------|
| **Sample Size** | 268 | 1,145 |
| **Mean Time to Graduate (in years)** | 5.43 | 4.43 |
| **Standard Deviation of Time to Graduate (in years)** | 1.162 | 1.015 |

**Analysis:**
- **Sample Size**: The study included 268 students who attended community college and 1,145 students who attended a 4-year institution.
- **Mean Time to Graduate**: On average, students who started at a community college took 5.43 years to graduate, whereas those who enrolled directly in a 4-year institution took 4.43 years to complete their degree.
- **Standard Deviation**: The variability in graduation time was slightly higher for community college students (1.162 years) compared to students at 4-year institutions (1.015 years).

**Interpretation:**
This data suggests that students who begin their education at a community college generally take about one year longer to graduate with a bachelor's degree compared to their peers who start and remain at a 4-year institution. The slightly higher standard deviation in the community college group indicates a broader range of completion times among these students.

This analysis highlights important considerations for educational planning and advising, particularly for students considering starting their higher education at a community college.
