Estimating the population mean using stratified median ranked set sampling
In this paper, stratified median ranked set sampling (SMRSS) method is suggested for estimating the population mean. The SMRSS is compared with simple random sampling (SRS), stratified simple random
The Factors that Lead to Cheating in Exams and How to Avoid Them
Cheating is one of the worst habitats that some students use it to pass their exams, and the biggest challenge to teachers and invigilators during tests to control the class and prohibit cheating.
Investigating the Use of Stratified Percentile Ranked Set Sampling Method for Estimating the Population Mean
Stratified percentile ranked set sampling (SPRSS) method is suggested for estimating the population mean. The SPRSS is compared with the simple random sampling (SRS), stratified simple random
Analysis of Suitability of Online Assessment by Maintaining Critical Thinking
TLDR
It is found that online assessment by using selective types of questions like multiple choices, true or false and final answer questions don’t reflect the actual understanding of students in solving the problems and teachers can’s determine the weakness points of students.
On the Mean Estimation using Stratified Double Median Ranked Set Sampling
Stratified Double Median Ranked Set Sampling (SDMRSS) method is suggested for estimating the population mean. The SDMRSS is compared with the Simple Random Sampling (SRS), Stratified Simple Random
Estimating the Population Mean by Using Stratified Double Extreme Ranked Set Sample
TLDR
It is shown that the SDERSS estimator is an unbiased of the population mean and more efficient than the estimators using SRS, SRSS and SSRS when the underlying distribution of the variable of interest is symmetric or asymmetric.
The Students Who Come to the University are Weak in Mathematics, Why and Where is the Problem?
Weakness of students in mathematics is a very old problem, discovering the source of this weakness is not an easy mission and needs to check the curriculum, teaching methods, learning process,
