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 - - - - -. - ANS-parameter; statistic
A researcher hypothesizes that the drug treatment of hospitalised schizophrenic patients improves their
mental alertness. He studies a random sample of 27 patients to see whether there is a relationship
between the number of days of drug treatment and patients' scores on the Mental Alertness Test.
, Which is an appropriate null hypothesis for this research? - ANS-H0: ρ = 0
A researcher suspects that children's level of anxiety during a test will interfere with their memories. He
gives a list of items to be memorized to a sample of children, and gives them a test to see how many
items they can remember. Directly afterwards he also tests the level of anxiety of each child with an
anxiety scale (where a higher score shows a greater level of anxiety).
The researcher draws a scatter plot of the relationship between level of anxiety and number of items
recalled. The result is presented below.
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; sample
A frequency distribution of the ages in months of a class of Grade 1 children indicates for each age in
months what the corresponding - - - - - is. - ANS-number of children of that age
If a pupil will be chosen to go on a field trip from a class of 13 girls and 17 boys, what is the probability
that
Noni (one of the 13 girls) will be chosen, given that a girl will be selected? - ANS-0.077
Which statement best represents an application of the law of large numbers? If I flip a coin 1000 times it
will fall heads up - - - - - 500 times. - ANS-approximately
Suppose that over the years 10 000 students wrote the examinations in PYC3704 and that 6000 of them
passed, of which 300 obtained exactly 50%. This means that for randomly selected students the
