PYC4807 Assignment 2 2024 What is the probability that a specific learner will obtain a score of 14 or less on the questionnaire in the scenario above? - ANS-0.2266 When applying a statistical test, a decision is reached by comparing the - - - - - to the - - - - -. - ANS-p-value; level of significance What does it mean to say "the difference between the means of groups A and B is statistically significant"? - ANS-The sample result is more probable under the alternative hypothesis. The value that is conventionally indicated with the symbol α refers to the - - - - -. - ANS-maximum probability of making an error of Type I if the rejection of H0 is to be considered A null hypothesis is - - - - -. - ANS-the assumption that there is no relationship or difference between parameters of the variables you are testing If you decided to set the level of significance to α = 0.001 rather than a more conventional level of α = 0.05, what would the consequences be? Choose the correct option(s). - ANS-You would be more likely to make a type two error. &There would be fewer instances when the null hypothesis could be rejected. A p-value generally tells us the - - - - -. - ANS-likelihood of obtaining the pattern of results due to sampling error if there is in fact no relationship between the relevant variables in the population How can p.05 be interpreted? Select the correct option below. - ANS-There is a less than 1 in 20 probability of the result occurring by chance alone if the null hypothesis were true. An inference is - - - - -. - ANS-a generalisation from a specific situation to the phenomenon in general, which have a high probability of being true In quantitative research, 'measurement' refers to which of the options given below? - ANS-(a) A procedure for allocating numbers to aspects of observations based on a rule. (c) A process of changing an abstract construct into a visible variable. "The mental age of child number one is eight years". In this statement "mental age" is a(n) - - - - -, whereas "eight years" is a - - - - -. - ANS-variable; specific value of that variable A measurement that summarizes an aspect of a population is called a - - - - - while a measurement that describes the same aspect of a sample is called - - - - -. - ANSparameter; statistic A - - - - - is a speculative statement about the relationship among - - - - -, based on observations or expectations. - ANS-hypothesis; constructs Rose is interested in studying creativity among fine arts students. She randomly selects 100 students who are attending a school for fine arts and tests each of them on a creativity test. In this example, the entire collection of fine arts students which Rose is interested in is referred to as the - - - - -, while the 100 cases which she requires to perform the creativity test are the - - - - -. - ANS-population; sampl
