    This is the difference between a sample statistic and corresponding population parameter

    • Sampling Error

    • Standard Error

    • Difference Error

    • None of the Above

    Correct Answer
    A. Sampling Error
    Explanation
    Sampling error refers to the discrepancy between a sample statistic and the corresponding population parameter. It occurs due to the fact that a sample is only a subset of the entire population, and therefore may not accurately represent the true characteristics of the population. Sampling error can occur due to various factors such as random sampling, sample size, and variability within the population. It is important to consider and account for sampling error when generalizing the findings from a sample to the larger population.

    An analysis used to reduce the data size or compress the data

    • ANOVA

    • Multivariate Analysis

    • Factor Analysis

    • Bivariate Analysis

    Correct Answer
    A. Factor Analysis
    Explanation
    Factor analysis is a statistical technique used to reduce the data size by identifying underlying factors that explain the patterns in the data. It helps in understanding the relationships among a large number of variables by grouping them into a smaller number of factors. This reduction in data size makes it easier to interpret and analyze the data. Therefore, factor analysis is an appropriate analysis technique for reducing the data size or compressing the data.

    Positive correlation is present when

    • Two variable move in opposite direction

    • Two variables move in the same direction

    • One variable goes up and another goes down

    • Variables never change

    Correct Answer
    A. Two variables move in the same direction
    Explanation
    A positive correlation is present when two variables move in the same direction. This means that as one variable increases, the other variable also increases, and as one variable decreases, the other variable also decreases. In other words, there is a direct relationship between the two variables, and they tend to change together.

    Which of the following includes examples of quantitative variables

    • Age, Temperature, Income, Height

    • Grade Point Average, Anxiety Levels, Reading Speed

    • Gender, Religion, Ethnic Group

    • Both A & B

    Correct Answer
    A. Both A & B
    Explanation
    Both A and B include examples of quantitative variables. Age, temperature, income, and height are all quantitative variables because they can be measured and expressed numerically. Grade point average, anxiety levels, and reading speed are also quantitative variables because they can be measured on a numerical scale. Gender, religion, and ethnic group, on the other hand, are examples of qualitative variables as they cannot be measured numerically.

    Qualities of a good report include:

    • Structure, Sequence and Content

    • Minimum 80 pages

    • Articulated literary sentences

    • All of the above

    Correct Answer
    A. Structure, Sequence and Content
    Explanation
    A good report should have a well-organized structure, with a clear sequence of information and a logical flow. It should also have relevant and accurate content, presenting the necessary information in a concise and coherent manner. The report should be free from any grammatical errors and should consist of articulate literary sentences. Therefore, the qualities of a good report include structure, sequence, and content.

    Which of the following does not determine the size of an adequate sample?

    • The nature of population

    • Researchers insight into sampling

    • The type of sampling design

    • The degree of precision desired

    Correct Answer
    A. Researchers insight into sampling
    Explanation
    The size of an adequate sample is not determined by the researcher's insight into sampling. The size of the sample is typically determined by factors such as the nature of the population, the type of sampling design, and the degree of precision desired. The researcher's insight into sampling may influence the selection of an appropriate sampling design or the determination of the degree of precision desired, but it does not directly determine the size of the sample.

    Rate this question:

  • 49. 

    When sample size is more than 30, which method is used to measure the difference between means of the observations?

    • Z-test

    • T-test

    • F-test

    • Chi-Square test

    Correct Answer
    A. T-test
    Explanation
    When the sample size is more than 30, the appropriate method to measure the difference between means of the observations is the t-test. The t-test is used when the population standard deviation is unknown and the sample size is small. It calculates the t-value by comparing the means of two groups and determines whether the difference between them is statistically significant. The t-test is commonly used in hypothesis testing and allows researchers to draw conclusions about the population based on the sample data.
