Validity and Statistics Quiz

Which of the following correctly describes validity?

• It studies the questions to see if they are to elicit the necessary information.

• It check if the questionnaire meets the objective of the research.

• It is not measured by a numerical index but relies instead on logical judgment.

• It is based on the systematic comparison of the test to the behavior that is intended to measure.

An employment test is administered to a group of workers and then test scores are correlated with the ratings of the workers’ supervisors taken in the same week. Based on the given scenario, what kind of validity is tested?

• Concurrent Validity

• Predictive Validity

• Face Validity

• Postdictive Validity

Which of the following refers to a form of criterion-referenced validity that is determined by the degree to which the scores on the given test are correlated to test scores administered at a previous point in time?

• Concurrent Validity

• Predictive Validity

• Convergent Validity

• Postdictive Validity

Which among the measurement scales makes zero (0) absolute and meaningful?

• Interval

• Ordinal

• Nominal

• Ratio

Which of the following should a researcher consider in determining the sample size of the study?

• Study design and methods of sampling

• Study design, methods of sampling, and measures of central tendency

• Study design, methods of sampling, and outcomes measure

• Study design, methods of sampling, and measure of dispersion.

The science of statistics evolved into two basic categories known as descriptive statistics and inferential statistics. Which of the following statements best describes the difference between the two?

• Descriptive statistics is the minor league while Inferential statistics is the major league.

• Descriptive statistics’ main focus is to summarize data while Inferential statistics makes actual claims about a population based on the sample.

• Descriptive statistics report only on the observations at hand and nothing more while Inferential statistics makes a statement about a population based solely on results from a sample taken from that population.

• Descriptive statistics explore the data collected, summarized, and described those data while Inferential Statistics uses the sample data's information to increase the researchers’ knowledge about the sample.

Which among the given statement below best described the Table qualitatively?

• Table 1 shows the Mathematical Literacy of the participants based on their pre-test examination

• It shows that the majority of the participants (58.00%) are on the beginning level.

• Seven (14.00%) of them are on the Good level.

• Two (4.00%) of the participants are on excellent and developing level in terms of Mathematical Literacy

Researcher A found a pre-existing questionnaire related to her study, and later decided to adopt the instrument. What could be the reason why she chose to adopt rather than to adapt?

• When the instrument is adopted, then the reliability and validity research studies that have been conducted on that instrument can be applied to her study, so you do not have to collect validity.

• Adopting an instrument links her study to all other research studies that have used the same instrument.

• Adopting the instrument saves her time and energy in making significant changes.

• She can copy the results of the other study.

Researcher B wishes to seek the opinions of the stakeholders in the full implementation of the face-to-face classes despite the surge of Covid-19, which of the following data collection instrument is appropriate to use?

• Experiment

• Interview

• Focus Group discussion

• Survey Questionnaire

Which type of statistical inference involves drawing conclusions from samples to the larger population?

• Central Tendency Analysis

• Descriptive Statistic

• Dispersion Measurement

• Inferential Statistics
