 Family Characteristics: Indices Of Adolescents Sexual Behaviour
Publication Authors:

Year Published:

Abstract:
This study examined the effect of family characteristics and parental status on adolescents’ sexual behavior in Okun land of Kogi State. Data were obtained from male and female adolescents in ten Government Secondary Schools among the Okun-Yoruba tribe of Kogi State. The Okun-Yorubas occupied five LGAs of the state. Two schools were selected from each of the LGAs. In all, 781 copies of questionnaire were distributed and 768 were retrieved from respondents. This sample responded to a semi-structured questionnaire which contained both open and closed ended questions on sexual activities among adolescents as facilitated by family and parental background and activities. The findings reveal that adolescents’ sexual behaviors are affected by their family or parental sexual life style, income and education level, tutelage, etc. Association between adolescents’ sexual behavior and parental indices as mentioned above were tested using the Chi-square test. The t-test was used to determine the significance of the findings while Cramer’s V value was used to test the strength of the associations. Results of the Chi-square tests were corroborated by focus group discussion and Indepth interview conducted among respondents and teachers. This allows for triangulation among responses gathered. Conclusions were drawn based on the findings and recommendations proffered

Publication Title:
 A Modified Stratified Randomized Response Techniques
Publication Authors:
 F. B. Adebola, O. O. Johnson And N.A. Adegoke
Year Published:
 2014
Abstract:
This paper presents a modification of Kim and Warde’s (2004) Stratified Warner’s Randomized Response Technique (SWRRT) and Kim and Elam’s (2007) Stratified Unrelated Question Randomized Response Technique with known distribution (SURRT) using optimal allocation. Our models further reduce the non-response bias by introducing the concept of sub-samples of non-respondent developed by Hansen and Hurwitz (1946) to the above mentioned models. In this paper we perform an empirical practice of our model and we also perform the empirical comparison of our models with both Kim and Warde (2004) and Kim and Elam (2007) models. We discovered a new note in the empirical comparative study of our models.

Publication Title:
 A Survey Of Examination Malpractices Using The Randomized Response Technique.
Publication Authors:
 Adebola, F.B And Adegoke N.A.
Year Published:

Abstract:
We administered a questionnaire survey using both the randomized response (RR) technique and the direct questioning (DQ) technique to directly estimate the prevalence of examination malpractices in The Federal University of Technology, Akure in Ondo State, Nigeria. The effectiveness of the RR technique in reducing response and non-response biases was also assessed and we examined the relationship between examination malpractices and key demographic variables. It was discovered that RR technique was effective in reducing non-response bias, but its effectiveness in reducing response bias could not be established statistically. Some relationships were found between the demographic variables examined and examination malpractices.

Publication Title:
 An Optimal Setting For Production Process Using Inverted Loss Function.
Publication Authors:
 Obafemi, O.S., Ajao I.O., Adebola, F.B.
Year Published:
 2013
Abstract:
In manufacturing, loss Function expresses the economic consequences associated with deviation from target; since different process have different sets of economic consequences a better approach to developing loss function and setting optimal values is desirable. This work focused on the use of loss function based on inverted normal probability density Function known as the inverted Normal loss function in determining an optimal setting for a production process. Basic programming language is used to determine the expected loss of weights with varying loss values, on weights of cigarette. The optimal value for the manufacturing of cigarette process was obtained to be 1030mg.

Publication Title:
 On A New Method Of Bias Reduction: Alternative To Approximately Unbiased Ratio Estimators
Publication Authors:
 Adebola ,F.B. And Oshungade ,I.O
Year Published:
 2012
Abstract:
This paper proposes a new method of bias reduction from order n?1 to order n?2 resulting in a new approximately unbiased ratio estimator. The efficiency of this estimator for the ratio of population means of two characters is compared with the existing six other Ratio estimators under a linear regression model.

 On A Numerical Comparison Of The Proposed Randomized Response Technique With Hussain And Shabbir (2007)
Publication Authors:

Year Published:
 2012
Abstract:
Randomized Response Techniques (RRTs) were developed for the purpose of improving response rate by protecting surveyee’s privacy and avoiding answer bias.In this paper, we succinctly investigated the trend of the response rate (?) with both the proposed Randomized Response Technique (RRT) and the conventional one. We found that the proposed (RRT) is better than the conventional one at each response rate since it gives smaller variance.

Year Published:

Abstract:
This paper compares seven approximately unbiased ratio estimators along side with the classical ratio estimator under a non-normal linear regression model. The variances, bias, mean squared errors and efficiencies of these estimators for the ratio of population means of two characters were compared using Monte Carlo. Our findings revealed that RA is the best

Year Published:

Abstract:
In this paper, a new randomized response technique has been proposed that combines the unrelated question randomized response technique and tripartite randomized response technique. The relative efficiency of the newly proposed Randomized Response technique over the existing Randomized Response technique was obtained. It was observed that the relative efficiency of the proposed technique over the tripartite RRT increases with increase in ?A and ?U. The applicability of the proposed technique was also shown. However, it has been shown that the proposed technique performs better than the conventional ones

Year Published:

Abstract:
In any research involving sensitive questions, respondents tend to refuse to answer such questions or give evasive response. Many randomized response sampling techniques were developed but could only handle two answer options; ‘Yes’ and ‘No’, among which are [8], e.t.c. In this paper, a tripartite randomized response sampling technique was developed to handle the three answer options: ‘Yes’, ‘No’ and ‘Undecided’,based on the modification of [8] model.
