WEEK FOUR DQ1 Explain the importance of random sampling. What problems/limitations could prevent a truly random sampling and how can they be prevented? Probability sampling‚ also known as random sampling‚ requires that every member of the study population have an equal opportunity to be chosen as a study subject. For each member of the population to have an equal opportunity to be chosen‚ the sampling method must select members randomly. Probability sampling allows every facet of the study population

model with user manipulating keys was established. It includes feedback of the recommended fashion design that matches the user’s sensibility by using visual element adjustment tools provided by the system. Also‚ through Type III analysis of variance (ANOVA)‚ the most important design category of developing each sensibility on women’s dress was found. For the example of contemporary sensibility‚ the most effective category was skirt length‚ then sleeve type‚ color tone‚ collar type‚ and the skirt type

Through this simulation I chose to use the two-way ANOVA and nonparametric test to help me evaluate the effects of the diverse factors on two response variables‚ which were productivity and client satisfaction. My findings helped me to narrow down and identify the areas that needed most improvement. Three Lessons Learned The lessons that were learned about an ANOVA and nonparametric test were that the two-way ANOVA helps to determine the data that you have when it comes from numerous

Chapter 1 THE PROBLEM AND ITS BACKGROUND Introduction A hand sanitizer or hand antiseptic is a supplement or alternative to hand washingwith soap and water. Various preparations are available‚ including gel‚ foam‚ and liquid solutions. The active ingredient in hand sanitizers may be isopropanol‚ ethanol‚ n-propanol‚ or povidone-iodine. Inactive ingredients in alcohol rubs typically include a thickening agentsuch as polyacrylic acid for alcohol gels‚ humectants such as glycerin for

preparations of hybrid nanoparticles containing dapsone which is finally converted into gel for topical drug delivery. The formulations were characterized for particle size‚ zeta potential and entrapment efficiency and were optimized by applying factorial design of experiment (23). The results showed that the optimal formulation (HN 4) of dapsone loaded hybrid nanoparticles had average particle size of 277nm‚ zeta potential of 26.7 mV‚ entrapment efficiency of 75.81%‚ and polydispersity index of
