(i) is incorrect because the 100 persons selected are referred to as a sample, not the population. The population would be all 25,000 registered voters. (ii) is incorrect because the order that runners finish in a race is an example of ordinal data, not continuous data. Continuous data would be something like the runners' times. (iii) is correct because qualitative data, which are non-numerical and categorize variables, are often summarized in graphs and bar charts to visualize the data effectively.
