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 […]

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

One-tailed test and two-tailed test are associated with:ย (A) Causation (B) concepts (C) constructs (D) hypothesis Correct Ans: (D) Explanation:One-tailed and two-tailed tests directly relate to hypothesis testing, a core process in statistical research. These tests help researchers decide whether to accept or reject a hypothesis based on data results. A one-tailed test examines whether

In quantitative research, the questions are Correct Ans: (D) Explanation: Quantitative research focuses on collecting measurable and objective data. To ensure accuracy and reliability, researchers use standardized questions, which maintain consistency across all respondents. Standardized questions are structured, uniform, and predefined. They ensure that all participants interpret and respond to the same set of questions

Non-parametric tests are generally applied to analyse (A) Nominal data (B) Ordinal data (C) Interval data (D) Ratio data Correct Ans: (A) Explanation: Non-parametric tests are statistical methods used to analyze nominal data, which consists of categorical variables without a specific order. These tests do not assume a normal distribution, making them ideal for research

The process of examining every member of a specified population is called (A) Probability (B) Partiality (C) Census (D) Non-probability Correct Ans: (C) Explanation Researchers conduct a census by examining every member of a specified population, ensuring comprehensive and accurate data collection. Unlike sampling methods that select a subset of individuals, a census includes every
