1. Mark believes that groceries at Costco will be less expensive than groceries at Safeway. Write a general, directional, and measurable hypothesis related to Mark's observation.
2. Leslie has observed that more small dogs are adopted at animal shelters than large dogs. Write a general, directional, and measurable hypothesis related to Leslie's observation.
3. Amy believes that as the number of years of driving experience people have increases the number of speeding tickets they receive decreases. Write a general, directional, and measurable hypothesis related to Amy's observation.
4. Roger has observed that students who take honors classes in college are less likely to drop out of college than students who do not. Write a general, directional, and measurable hypothesis related to Roger's observation. Sometimes a general observation may lead to several different hypotheses. Read the scenario which follows and write three measurable hypotheses based upon the different groups being compared.
5. Frank notices that when the seventh grade girls are able to do better on the "bend and reach test" flexibility test than seventh grade boys, eighth grade boys, or eighth grade girls.
6. Read the scenario which follows and write three measurable hypotheses based upon the three different variables being considered.
Scientists from the Department of Fish and Game have noticed that trout are more likely to get parasites when they are living in shallower, warmer, and muddy waters.
Anne has noticed that 8th grader girls seem to get better grades on organizational skills tests such as notebook quizzes.
General hypothesis:” Boys and girls receive different grades on organizational skills tests."
Directional hypothesis: "Girls get better grades than boys on tests of organizational abilities."
Measurable hypothesis: "Eight grader girls receive significantly higher grades on notebook quizzes than eight grader boys."
A non-directional (radio) beacon (NDB) is a at a known location, used as an aviation or marine aid. As the name implies, the signal transmitted does not include directional information, in contrast to other navigational aids such as , (VOR) and . NDB signals , so they can be received at much greater distances at lower altitudes, a major advantage over VOR. However, NDB signals are also affected more by atmospheric conditions, mountainous terrain, coastal refraction and electrical storms, particularly at long range.
