Project Defense Interactive Prep Kit

Project Defense Master Hub

Welcome, Peace! This preparation kit is tailored to help you fluently defend your research on Competitive Forces and Service Innovation of the Hotel Industry in Yenagoa. Explore the empirical data summaries below, master the 20 structured defense questions, or test your readiness with flashcards.

Target Population

109 Hotels

Kei et al. (2024) Directory

Sample Size

86 Hotels

Taro Yamane ($e = 0.05$)

Response Rate

97.67%

84 valid retrievals

Reliability ($\alpha$)

0.916

Cronbach's Alpha (SPSS)

Empirical Findings: Spearman Correlation ($r$)

Relationship between Porter's 5 Competitive Forces and Service Innovation (All $p < 0.001$).

Key takeaway for panel: Supplier Power has the highest correlation ($r = 0.742$), proving that volatile supply & energy costs drive hoteliers in Yenagoa to innovate internal processes most aggressively.

Study Section Breakdown

Section A: Context & Framework 4 Questions

Problem rationale, Yenagoa dynamics, Porter's model & Rogers' theory.

Section B: Methodology & Sampling 4 Questions

Taro Yamane, simple random vs purposive sampling, Cronbach's Alpha.

Section C: Empirical Findings 5 Questions

Spearman rho justifications, supplier power breakdown, p-value meanings.

Section D: Managerial & Academic Value 3 Questions

Recommendations for hoteliers, state planners, and sub-Saharan literature.

Section E: Defense Evaluation 4 Questions

Limitations, response bias mitigation, grant research roadmap, 1-sentence synthesis.

Defense Day Quick Reference & Formulas

Keep these key statistical formulas, theoretical anchors, and behavioral strategies ready during your presentation.

1. Formula Reference Sheet

Taro Yamane (1967) Sample Size Formula

n = N / [1 + N(e)²]

Where $N = 109$ (Population), $e = 0.05$ (Margin of Error).
$n = 109 / [1 + 109(0.0025)] = 109 / 1.2725 \approx 85.66 \rightarrow$ 86 Hotels.

Spearman’s Rank Correlation ($\rho$)

$\rho = 1 - \frac{6 \sum d_i^2}{n(n^2 - 1)}$

Non-parametric test chosen because data collected on 4-point Likert scales is ordinal and non-normally distributed.

Cronbach's Alpha Scale Reliability

Threshold: $> 0.70$. Instrument achieved overall 0.916 across all constructs, confirming high internal reliability.

2. Dual Theoretical Framework

Michael Porter’s Five Forces (1979/1980)

Role in Study: External environmental lens. Measures competitive pressures operating in the Yenagoa market: New Entrants, Substitutes, Buyer Power, Supplier Power, and Rivalry.

Everett Rogers’ Innovation Diffusion Theory (2003)

Role in Study: Internal organizational lens. Explains how hotels adopt, modify, and spread innovative service practices in response to external pressures.

1-Sentence Core Thesis Defense Synthesis

"Competitive forces in Yenagoa are not mere market obstacles, but vital strategic drivers that compel hoteliers to continuously innovate, modernise service delivery, and sustain business competitiveness."

3. Tactical Presentation Tips for Defense Day

👁 Maintain Eye Contact

Look directly at panel members when answering. Speak with calm authority.

🗣 Confident Phrases

Use expressions like "Our empirical evidence demonstrates..." or "Statistically, the $p < 0.001$ level confirms..."

📌 Structured Answers

State direct answer first $\rightarrow$ Give statistical/theoretical basis second $\rightarrow$ Conclude with practical implication.
