The normal distribution shape of standard deviations from the mean is sometimes referred to as (A) error distribution (B) value table (C) property range (D) bell curve Correct Ans: (D) Explanation: Mass media researchers frequently describe the normal distribution as the bell curve. This is because its shape closely resembles a bell. In any data […]

A systematically-qualitative data set is amenable to analysis. (A) non-progressive (B) entropical (C) grounded theory (D) contrived Correct Ans: (C) Explanation:Researchers analyze systematically-qualitative data sets using grounded theory in mass media research. Grounded theory helps them develop new theories directly from the data, without relying on existing frameworks. In this approach, researchers gather data first

The probability of rejecting the null hypothesis when it is true, is called (A) co-variation (B) assumption (C) power (D) chance value Correct Ans: (C) Explanation: In media research, understanding statistical power is crucial when interpreting results from hypothesis testing. Statistical power refers to the probability of correctly rejecting the null hypothesis when it is

The test normally used to find out the significance of mean difference among four independent variables is (A) Z – test (B) Chi – square test (C) Partial correlation (D) Analysis of variance Correct Ans: (D) Explanation: In mass communication research, when you want to find out whether there are significant mean differences across four

The constant comparative analysis is involved in approach. (A) the agenda – setting (B) personal effects (C) positivist (D) grounded theory Correct Ans: (D) Explanation: In media research, constant comparative analysis forms the heart of the grounded theory approach. This technique involves comparing each piece of data with others to identify patterns, categories, and relationships.

In media research, conclusions from induction are (A) illogical (B) tentative (C) eternal (D) non-operative Correct Ans: (B) Explanation: In media research, when researchers use inductive reasoning, they begin with specific observations and move toward broader generalizations or theories. Unlike deduction, which starts with a theory and tests it through data, induction works from the

The list of population elements from which the sample is drawn is called (A) population register (B) sample register (C) sampling frame (D) population frame Correct Ans: (C) Explanation: In mass communication and social science research, a sampling frame refers to the complete list of population elements from which a researcher selects a sample. It

In research, abstract models are not applied to (A) non – causal relations (B) conceptual issues (C) elements of reasoning (D) real problems Correct Ans: (D) Explanation: In research—especially within mass communication—abstract models serve a specific purpose. They help researchers think about conceptual issues, explore non-causal relationships, and understand reasoning structures. These models simplify reality
