Froggy Jumps Hypothesis Testing (uppersixth science further maths new)Version en ligne Test your knowledge on hypotheses in science and their significance! par YAKILI LMS 1 What is a hypothesis? a A proven fact. b A testable prediction based on observations. c An untestable theory. 2 Why is it important to test a hypothesis? a To ignore the results. b To make it a law. c To validate or refute the prediction scientifically. 3 What is a null hypothesis? a A hypothesis that cannot be tested. b A hypothesis that is always true. c A statement that there is no effect or no difference. 4 What does it mean to falsify a hypothesis? a To provide evidence that disproves it. b To prove it is true. c To ignore it completely. 5 In scientific research, what follows after forming a hypothesis? a Conducting experiments to test it. b Publishing the results immediately. c Writing a conclusion. 6 What is an alternative hypothesis? a A statement that indicates a potential effect or difference. b A hypothesis that is always wrong. c A hypothesis that is never tested. 7 What role does data play in hypothesis testing? a Data is only for conclusions. b Data provides evidence to support or reject the hypothesis. c Data is irrelevant. 8 What is a hypothesis in the context of scientific inquiry? a A random guess. b A proposed explanation for a phenomenon. c A final answer to a question. 9 What is a key characteristic of a good hypothesis? a It must be complex. b It must be universally accepted. c It must be testable and falsifiable. 10 Which of the following is NOT a reason to test a hypothesis? a To improve scientific understanding. b To gain new insights. c To confirm existing beliefs without evidence. 11 What is the primary role of a hypothesis in scientific research? a To collect data. b To provide a testable prediction. c To summarize previous findings. 12 In the context of further maths, what does a hypothesis help to establish? a A definitive answer. b A random guess. c A foundation for mathematical modeling. 13 Which of the following is NOT a characteristic of a good hypothesis? a It should be based on prior knowledge. b It should be testable. c It must be vague and ambiguous. 14 How does a hypothesis contribute to the scientific method? a It replaces the need for data. b It guides the experimentation process. c It is the final conclusion. 15 What type of hypothesis predicts a relationship between two variables? a A null hypothesis. b A random hypothesis. c A directional hypothesis. 16 In further maths, what is essential for validating a hypothesis? a Historical data. b Personal opinion. c Statistical analysis of results. 17 What is the outcome if a hypothesis is not supported by experimental data? a It may be rejected or revised. b It becomes a theory. c It is proven true. 18 Which hypothesis suggests no effect or relationship? a Null hypothesis. b Alternative hypothesis. c Directional hypothesis. 19 What is the first step in forming a hypothesis? a Collecting data. b Identifying a research question. c Drawing conclusions. 20 Why is it important to communicate hypotheses clearly? a To ensure reproducibility of experiments. b To fill up reports. c To impress peers. 21 What is a Type I error? a Rejecting a true null hypothesis. b Failing to reject a false null hypothesis. c Accepting a true null hypothesis. 22 What does a Type II error represent? a Rejecting a true null hypothesis. b Failing to reject a false null hypothesis. c Accepting a false null hypothesis. 23 Which error is also known as a false positive? a Type I error. b True negative. c Type II error. 24 Which error is referred to as a false negative? a True positive. b Type I error. c Type II error. 25 In hypothesis testing, what does alpha (α) represent? a The probability of a Type II error. b The probability of a Type I error. c The significance level. 26 What does beta (β) signify in hypothesis testing? a The confidence level. b The probability of a Type II error. c The probability of a Type I error. 27 Which of the following increases the risk of a Type I error? a Decreasing the significance level. b Increasing the significance level. c Increasing the sample size. 28 What is the consequence of a Type I error? a Correctly identifying no effect. b Incorrectly concluding an effect exists. c Missing a true effect. 29 What is the consequence of a Type II error? a Failing to detect an actual effect. b Correctly identifying an effect. c Incorrectly concluding an effect exists. 30 How can one reduce the likelihood of a Type II error? a Increase the significance level. b Increase the sample size. c Decrease the sample size. 31 What is the significance level commonly denoted as? a Alpha (α) b Gamma (γ) c Beta (β) 32 What does a lower significance level indicate? a More lenient criteria b No effect on hypothesis testing c Stricter criteria for rejecting the null hypothesis 33 In hypothesis testing, what is a critical region? a The range of values that leads to rejection of the null hypothesis b Values that support the null hypothesis c The entire data set 34 What is the typical significance level used in many tests? a 0.10 b 0.05 c 0.01 35 What does a critical value represent? a The threshold at which the null hypothesis is rejected b The mean of the sample c The standard deviation 36 If a test statistic falls within the critical region, what is the conclusion? a Accept the null hypothesis b Reject the null hypothesis c Fail to reject the null hypothesis 37 What is the consequence of a Type I error? a Rejecting a true null hypothesis b Failing to reject a false null hypothesis c Accepting a true null hypothesis 38 What does a significance level of 0.01 imply? a 10% risk of a Type I error b 1% risk of a Type I error c 5% risk of a Type I error 39 What is the relationship between significance level and sample size? a Smaller samples are always better b Larger samples can detect smaller effects at the same significance level c Sample size has no effect 40 What is the role of critical values in hypothesis testing? a They help determine the rejection region for the null hypothesis b They summarize the data c They calculate the mean 41 What is the primary purpose of a hypothesis in scientific testing? a To provide a conclusion. b To make predictions that can be tested. c To summarize past research. 42 In hypothesis testing, what does the null hypothesis typically represent? a A statement of no effect or no difference. b A statement of significant effect. c An assumption of bias. 43 What is a Type I error in hypothesis testing? a Accepting a true alternative hypothesis. b Rejecting a true null hypothesis. c Failing to reject a false null hypothesis. 44 What is the significance level (alpha) commonly set at in hypothesis testing? a 0.01. b 0.05. c 0.10. 45 Which test is commonly used to compare means between two groups? a ANOVA. b Chi-square test. c t-test. 46 What does the p-value indicate in hypothesis testing? a The sample size required. b The strength of the alternative hypothesis. c The probability of observing the data if the null hypothesis is true. 47 What is the alternative hypothesis? a A statement that indicates the presence of an effect. b A statement that indicates no effect. c A conclusion drawn from the data. 48 Which of the following is NOT a step in hypothesis testing? a Formulating a hypothesis. b Collecting data after forming a hypothesis. c Analyzing the results. 49 What is the role of a confidence interval in hypothesis testing? a To calculate the p-value. b To estimate the range of values for a population parameter. c To determine the sample size needed. 50 What does a low p-value (e.g., < 0.05) suggest? a Weak evidence against the null hypothesis. b No evidence for the alternative hypothesis. c Strong evidence against the null hypothesis.
