Abstract
About This Research Topic
Mobile banking defined as use of mobile telecommunications devices to conduct financial transactions has rapidly expanded across Nigeria driven by high mobile phone penetration expanding telecom infrastructure and regulatory support from Central Bank of Nigeria financial inclusion strategy. This growth offers pathway for previously unbanked and underbanked Nigerians particularly in areas with limited traditional banking infrastructure to access formal savings payment and credit services.
Despite expansion adoption remains uneven across demographic and geographic segments with variation associated with age educational attainment income and prior exposure to digital financial technology. Understanding statistical determinants is essential to financial institutions seeking to expand customer base and policymakers pursuing national financial inclusion targets where mobile channel is identified as most cost-effective mechanism versus physical branch expansion. Technology Acceptance Model and Unified Theory of Acceptance and Use of Technology provide well-established frameworks positing perceived usefulness perceived ease of use social influence facilitating conditions and perceived risk jointly shape behavioural intention. Statistical modelling particularly binary logistic regression provides appropriate quantitative tool for testing these theorised relationships. This article for SCHOLARNESTHUB presents rewritten SEO-optimized analysis of survey of 384 respondents with 68.2 percent adoption rate modelling predictors of mobile banking adoption. For similar quantitative frameworks see fintech project topics on SCHOLARNESTHUB.
Main Abstract
Mobile banking has emerged as central pillar of Nigeria's financial inclusion agenda offering channel through which previously unbanked and underbanked populations can access formal financial services without reliance on traditional brick-and-mortar infrastructure. Study statistically models determinants of mobile banking adoption among residents of selected city/LGA Nigeria drawing on Technology Acceptance Model and Unified Theory of Acceptance and Use of Technology as guiding frameworks. Structured questionnaire administered to sample of 384 respondents determined using Taro Yamane formula eliciting Likert-scale responses on perceived usefulness perceived ease of use perceived risk social influence and facilitating conditions alongside binary adoption outcome. Descriptive statistics characterised demographic and adoption profiles while binary logistic regression employed to model probability of adoption as function of theorised predictors and Chi-Square tests assessed association between adoption and categorical demographic variables. Results show overall adoption rate 68.2 percent among sampled respondents. Logistic regression model explaining 41.3 percent variation Nagelkerke R2 0.413 identified perceived usefulness OR 2.84 p<0.001 perceived ease of use OR 1.92 p 0.003 and social influence OR 1.68 p 0.011 as statistically significant positive predictors while perceived risk significant negative predictor OR 0.54 p 0.002. Chi-square analysis revealed statistically significant association between educational attainment and adoption status chi-square 24.61 p<0.001. Study concludes adoption significantly shaped by technology acceptance constructs consistent with established models and recommends targeted usability improvements and risk-communication strategies to accelerate adoption among underserved segments.

Background to the Study
Nigeria has over 200 million mobile subscriptions and Central Bank financial inclusion strategy reports identify mobile-channel banking as single most cost-effective mechanism for extending services to remaining unbanked population given low marginal infrastructure cost versus branch expansion. Mobile banking includes app-based and USSD channels enabling transfers bill payments airtime purchase savings. Adoption influenced by perceived usefulness degree individual believes using mobile banking enhances financial management effectiveness and perceived ease of use degree believes use free of effort as defined in TAM. UTAUT adds social influence degree important others believe they should use and facilitating conditions. Perceived risk assessment of financial loss fraud privacy breach remains barrier particularly among less educated and older demographics.
Statistical approach uses binary logistic regression modelling log-odds of adoption as linear function of predictors producing odds ratios interpretable for intervention design. Chi-square tests association between categorical demographics and adoption. Prior Nigerian studies show usefulness and ease of use consistently positive predictors while risk negative.

Statement of the Problem
Despite substantial regulatory and institutional investment expanding mobile banking infrastructure adoption rates in many Nigerian communities remain below levels consistent with national financial inclusion targets and variation persists across demographics. Without statistically rigorous evidence identifying which technology acceptance constructs and demographic factors most strongly predict adoption financial institutions and policymakers risk designing product features marketing campaigns and financial literacy interventions poorly targeted to actual barriers experienced by non-adopters. This study addresses evidentiary gap by applying theoretically grounded statistically rigorous binary logistic regression framework to survey data generating quantified validated evidence regarding relative strength of constructs as predictors of adoption behaviour.
Aim and Objectives of the Study
Aim is to statistically model determinants of mobile banking adoption among residents of study area.
· Determine current level of mobile banking adoption among sampled respondents.
· Assess respondent perceptions of usefulness ease of use risk and social influence associated with mobile banking.
· Develop binary logistic regression model identifying statistically significant predictors of mobile banking adoption.
· Test statistical association between demographic characteristics and adoption status.
· Draw evidence-based recommendations for accelerating mobile banking adoption based on statistical findings.
Research Questions
· What is current level of mobile banking adoption among residents of study area?

Research Hypotheses
H01: Perceived usefulness does not significantly predict mobile banking adoption.
H02: Perceived risk does not significantly predict mobile banking adoption.
H03: There is no statistically significant association between educational attainment and mobile banking adoption status.
All hypotheses tested at 5 percent significance level.
Significance of the Study
To financial institutions and fintech companies study provides statistically grounded evidence to inform product design usability improvements and marketing strategy highlighting that usefulness OR 2.84 strongest predictor followed by ease of use OR 1.92 and social influence OR 1.68 while risk OR 0.54 reduces adoption. To policymakers offers evidence to support targeted interventions for underserved segments particularly lower education groups where chi-square 24.61 p<0.001 shows significant association. Academically contributes to Nigerian technology adoption literature and provides replicable methodology combining TAM/UTAUT with binary logistic regression applicable to other digital financial services.

Scope of the Study
Delimited to residents of selected city/LGA State Nigeria who own or have access to mobile phone. Examines mobile banking adoption as binary outcome 1 adopter 0 non-adopter does not extend to detailed usage-intensity or transaction-volume analysis which would require access to actual transactional records beyond self-reported survey data.
Limitations of the Study
Limited by reliance on self-reported survey data regarding adoption status and perceptual constructs subject to recall or social desirability bias. Cross-sectional design captures adoption status and perceptions at single point and does not directly model temporal adoption process. Findings should be interpreted as reflective of illustrative sample rather than definitive census across study area. Sample 384 determined via Taro Yamane formula adequate for logistic regression but larger sample could improve precision.

Short Conclusion
Mobile banking adoption in study area significantly shaped by technology acceptance constructs consistent with TAM and UTAUT. Logistic regression explaining 41.3 percent variation identified usefulness OR 2.84 ease of use OR 1.92 social influence OR 1.68 as positive predictors and risk OR 0.54 as negative predictor. Educational attainment significantly associated chi-square 24.61 p<0.001. Recommendations include targeted usability improvements simplifying interfaces for low-literacy users, risk-communication strategies highlighting security features and consumer protection, leveraging social influence through community champions and peer demonstrations, and financial literacy programs focused on underserved educational segments. Realising financial inclusion potential depends on addressing behavioural barriers even where services technically available.
