The degree to which a quasi-experiment supports a causal claim depends on which of the following? Its duration and sample size I
ts importance and external validity The degree to which they rule out as many threats to internal validity as possible Its statistical significance and practical significance 1
The degree to which they rule out as many threats to internal validity as possible
Step-by-step explanation:
quasi-experiment supports a causal claim depends Its design and its results. It depends on Internal validity which is a scientific concept that addresses the relationship between two variables. Threat to internal validity includes history, maturation, testing, instrumentation, regression, selection, experimental mortality, and an interaction of threats.
The total possibility that the head and even no on dice appears is 3. and total possible choice are 12 {head ---> (1,2,3,4,5,6) & tail ---> (1,2,3,4,5,6)}. so the probability is 3/12= 1/4.
