Question 1

Dave has developed a research question.In addition, he has developed two hypotheses for his research question.The first hypothesis states there is no difference between the scores on the dependent variables.This is known as the________ hypothesis.

Accepted Answer

The given hypothesis statement describes the null hypothesis, which assumes that there is no difference between the scores on the dependent variable.

Question 2

When searching for research on more than one topic area, you should use the words)________ between search topics to find overlapping material.

Accepted Answer

When searching for multiple topics, the word "and" should be used between them to find overlapping material that includes both topics.

Question 3

When hypotheses in a research study are exhaustive, they are ________.

Accepted Answer

When hypotheses are exhaustive, they include all possible explanations or possibilities for the research question or problem.

Question 4

When stating the null or research hypotheses in symbols, the symbol $\mu  $  stands for ________.

Accepted Answer

"F1F1F1S1F1F1F10" represents the mean of the population, which is stated in the null and research hypotheses using the variable symbol "µ".

Question 5

The names of the hypotheses for a research study are________ and________ .

Accepted Answer

In a research study, the hypotheses are typically categorized as the null hypothesis and the research hypothesis. The null hypothesis assumes that there is no relationship or difference between the variables being studied, while the research hypothesis proposes that there is a relationship or difference. Therefore, the best choice is C) null, research. The other options, such as first and second or mutually exclusive and exhaustive, do not accurately reflect the nature of hypotheses in a research study.

Question 6

What does the following mean in words: H₀ $\mu $ ₁ = $\mu $₂?

Accepted Answer

The null hypothesis (H0) states that the means of two populations are equal. In this case, H0: μ1 = μ2, which means that the mean of population 1 (μ1) is equal to the mean of population 2 (μ2).

Question 7

In research, the two hypotheses developed must be ________and ________.

Accepted Answer

Hypotheses should be mutually exclusive (meaning they do not overlap or contradict each other) and exhaustive (meaning they cover all possible outcomes or explanations). This ensures that the research will be focused and have clear outcomes, allowing for accurate conclusions to be drawn. The other answer choices (B, C, D) do not accurately describe the criteria for developing hypotheses in research.

Question 8

Georgia has developed two hypotheses for her research question.The first hypothesis is known as the null hypothesis and states there will be no difference between the scores on the dependent variables.Her second hypothesis is known as a research hypothesis and states________ .

Accepted Answer

The null hypothesis states that there will be no difference between the scores on the dependent variables, while the research hypothesis states that there is a difference between scores on the dependent variables. Therefore, choice C is the correct answer.

Question 9

Sara is searching on the Internet for information on her research topic.The search results lead to only 10 hits.Sara's search resulted in a small number of records because________ .

Accepted Answer

Sara's search resulted in a small number of records because her topic is too narrow, meaning it is very specific and not many sources have covered it.

Question 10

The null hypothesis is represented in symbols as________ .

Accepted Answer

The null hypothesis is represented in symbols as H₀.

Question 11

The research hypothesis is represented in symbols as ________.

Accepted Answer

The research hypothesis, also known as the alternative hypothesis, is represented by H₁.

Question 12

When hypotheses for a study are said to be mutually exclusive, this means the hypotheses________ .

Accepted Answer

Mutually exclusive hypotheses cannot both be true because they are mutually incompatible or contradictory. Therefore, only one hypothesis can be true.

Question 13

Susan is conducting a research study and has developed two hypotheses.She is planning to test against the null hypothesis.The null hypothesis states________ .

Accepted Answer

The null hypothesis always states that there is no difference between the variables being compared. Hypothesis A and C both suggest that there is a relationship or significant relationship between variables, which would be the alternative hypothesis being tested against the null hypothesis. Choice D is not relevant to the formulation of a null hypothesis.

Question 14

When selecting a research hypothesis, researchers can have either a ________or ________research hypothesis.

Accepted Answer

Researchers can have either a nondirectional or directional research hypothesis, indicating whether they predict a specific direction of the effect or just an effect without specifying the direction.

Question 15

When searching for research on a topic, it is recommended that you use________ to increase the number of search results.

Accepted Answer

Using synonyms of the keywords in your search can yield more results as different authors may use different terms to describe the same concept or idea. Antonyms, prepositions and adjectives may not necessarily increase the number of search results.

Question 16

A statement by a researcher about the relationship between variables is known as a ________.

Accepted Answer

A hypothesis is a statement by a researcher that predicts a relationship between variables, often as a specific, testable prediction derived from a theory.

Question 17

You have been discussing a research project with your friend James.James has told you that his research hypothesis states, the mean of population 1 is not equal to the mean of population 2.How would you write this research hypothesis in symbols?

Accepted Answer

The symbol for "not equal to" is "≠", therefore the correct hypothesis in symbols would be H₁ F1F1F1S1μF1F1F10 ≠ F1F1F1S1μF1F1F10₂. Choice C is the only one that includes this symbol.

Question 18

Mark has developed a research question.In addition, he has developed two hypotheses for his research question.The second hypothesis Mark has developed states there is a difference between the scores on the dependent variables he is measuring.This is known as ________the hypothesis.

Accepted Answer

The second hypothesis that states there is a difference between the scores on the dependent variables is known as the research hypothesis. It is formulated to propose a relationship or difference between variables, contrasting with the null hypothesis, which typically posits no effect or relationship.

Question 19

You have been discussing a research project with your friend Tony.Tony has told you that his hypothesis states, the mean of population 1 is equal to the mean of population 2.How would you write this research hypothesis in symbols?

Accepted Answer

D is the only choice that correctly represents the research hypothesis in symbols. H₀ represents population 1 and H₁ represents population 2. F1F1F1S1μF1F1F10 represents the mean of population 1 and F1F1F1S1μF1F1F10 represents the mean of population 2. The = sign indicates that the means are equal. ₂ does not have any relevance to the hypothesis. Option A has an extra symbol of ≠, which implies that the means are not equal, contradicting the hypothesis. Option B has a < symbol, which implies that the mean of population 1 is less than the mean of population 2, which is different from the hypothesis.

Question 20

Tom has developed a________ that states there is a relationship between caffeine and alertness.

Accepted Answer

A hypothesis is a testable prediction based on theoretical or observed evidence, and Tom's statement meets this description. A theory is a well-established set of explanations for observed phenomena, which goes beyond a single hypothesis. Correlation simply states that there is a relationship between two variables, without any explanation or prediction for why that relationship exists. A statement could refer to any piece of information, without necessarily being a hypothesis or theory.
