Two way ANOVA Test will have three null hypotheses. One hypothesis will represent the independent variable‚ and its effects on the second hypothesis which is the dependent variable (main effect). The third null hypothesis is the interaction effect on both independent variables on the dependent variable

Statistics for Business and Economics Personal pre-assignment 1.9 What is a representative sample? What is its value? The representative sample is a subset of a population of interest that is exhibiting the typical characteristics of the population. The most typical way to cover the up-mentioned criterion is the simple random sample which consist of a sample of units that is selected randomly‚ e. g. the sample is selected form the population on a way that every sample of the size is having

There is a lot of anxiety among medical practitioners‚ both senior and junior concerning certain topics like statistics and epidemiology. The anxiety in some situations becomes quite acute causing stress to themselves as well as their students. Good research draws on statistics to prove certain findings and to establish associations. However statistics is definitely not everything in research. Identifying a topic of research‚ writing up the objectives‚ planning the right design‚ coming up with

Statistics Coursework Plan – In this project‚ I will be investigating how accurately students can estimate an angle size and the length of a line. I am investigating it to see if age‚ gender and mathematical capabilities have an effect on how accurate students can estimate a length of a line and an angle size. I will be using secondary raw data which is given to me to my teacher who has collected the data from other students. The accuracy of the data is unknown and also human errors are also
