External validity refers to the degree to which research results obtained from a particular sample and context can be applied to broader populations, different environments and future periods. High external validity suggests that findings are not limited to the specific conditions under which the study was conducted. It depends on factors such as sampling methods, realism of the setting and replication in different contexts. Because the stem highlights generalisation to other settings, populations and times, external validity is the correct term.

Option A:
External validity is enhanced when the sample is representative and when the research conditions resemble real-world situations, increasing the likelihood that similar results will be observed elsewhere. Studies with narrow samples or artificial settings may show strong internal validity but weaker external validity. The generalisability focus in the stem aligns directly with the concept of external validity, confirming it as the right option.

Option B:
Internal consistency is a type of reliability that concerns how well items on a test measure the same underlying construct, often assessed with coefficients like Cronbach’s alpha. It does not address whether findings generalise beyond the sample, so internal consistency is not the correct answer.

Option C:
Item difficulty refers to how hard individual test items are for examinees, usually expressed as the proportion of test takers who answer each item correctly. While important in test construction, it is unrelated to the generalisability of study findings across settings or populations. Thus, item difficulty does not fit the description in the stem.

Option D:
Standard error is a statistical index that indicates the variability of a sample statistic, such as the mean, across repeated samples from the same population. Although it relates to sampling accuracy, it is not itself the term for generalisability across broader contexts. Therefore, standard error is not the appropriate completion here.
