“…) X 2 = the table value of chi-square for 1 degree of freedom at the desired confidence level (3.841); N = the population size; P = the population proportion (assumed to be 0.50 since this would provide the maximum sample size); d = the degree of accuracy expressed as a proportion (.05). Table 2 above shows that more from ML-PHWs (136) than supervisors (28) were sampled using a simple random sampling technique (Shahzad, Al-Noor, Hanif & Sajjad, 2020). However, the response rate was 113 representing 68.9%, which is a good response seeing that much of the data was collected during Corona pandemic.…”

Purpose: This study sought to determine the efficacy of inspirational motivation on the performance of middle-level Public Health Workers (PHWs) in Lira District Local Government. Specifically, the study aimed to: determine the degree of inspirational motivation among ML-PHWs in Lira District; determine the level of performance among ML-PHWs in Lira District; and investigate the effect of inspirational motivation on the performance of ML-PHWs in Lira District. Research methodology: The study adopted a cross-sectional survey design while incorporating both quantitative and qualitative methods. The study used stratified and simple random sampling procedures to select health facilities, supervisors and ML-PHWs; a total of 164 respondents were selected. Results: The findings suggest that inspirational motivation has a significant effect on the performance of ML-PHWs ( p<0.01). Limitations: This study only focused on one construct of transformational leadership style (inspirational motivation), yet there are several constructs of that style, which may affect the performance of PHWs. Contribution: The findings of this study can be useful to public service managers wishing to enhance the performance of PHWs using limited resources.

“…Literature on RSS has rapidly grown and several estimators, originally conceived for the SRS, have been re-proposed to estimate the mean of the study variable by changing their sampling design into RSS framework (Ali et al, 2021;Iqbal et al, 2020;Kadilar et al, 2009;Khan & Shabbir, 2016a, 2016b, 2016cMandowara & Mehta, 2013Pelle & Perri, 2018;Samawi & Muttlak, 1996;Singh et al, 2014;Vishwakarma et al, 2017). Motivated by these studies, and in line with many other contributions present in the literature section of this article, we propose an efficient generalized family of estimators by changing the sampling design of the estimator proposed by Shahzad et al (Shahzad et al, 2019).…”

Estimation of population mean of study variable Y suffers loss of precision in the presence of high variation in the data set. The use of auxiliary information incorporated in construction of an estimator under Rank set sampling scheme results in efficient estimation of population mean. In this paper, we propose an efficient generalized family of estimators to estimate finite population mean of study variable under ranked set sampling utilizing information on an auxiliary variable. Bias and Mean Square Error (MSE) of the proposed generalized family of estimators are derived. The conditions of efficiency of proposed generalized family of estimators from competitor estimators are also derived. The applications of estimator are discussed using simulation study and real-life data sets for comparisons of efficiency. It is concluded that when correlation between study and auxiliary variables increases, the proposed generalized family of estimators proves to be the efficient estimator of population mean of the study variable.

In this study, ratio estimators are proposed by utilizing some robust techniques to get the maximum benefit of the auxiliary variable for the estimation of the population mean in simple random sampling. The expressions for mean squared error are derived for the first degree of approximation. Theoretical comparisons demonstrate that the suggested estimators having robust regression estimates perform better than the existing estimators under certain conditions. Theoretical findings are supported with the aid of the original dataset in an application. In addition, a simulation study is also conducted to evaluate the performance of the suggested estimators.
