Scientists are looking at the effects of global warming on clutches of sea turtle hatchlings in different parts of the world. The data below has been collected: 1.Temperature of Incubation (in Kelvin) 2. Gender Group of Hatchling Clutch (0=0% male; 1= greater than 0% but less than or equal to 10% male; 2= greater than 10% but less than 20% male; 3= greater than 20% but less than or equal to 30% male and so on) 3. Number of hatched eggs 4. number of unhatched eggs 5. Location of Turtles (0=west North America; 1= west South America; 2= tropical regions of Pacific; 3= northwestern Atlantic; 4= Indian Ocean Which of the above variables are measured using a nominal scale, ordinal scale and ratio scale. (An answer can be none of variables) thank you
A researcher wants to know if a treatment significantly changes the wellbeing of someone with depression. The average person with depression scores a 7.2 on a wellbeing scale with a SD of 1.4 points. The researcher administers the treatment to 25 clients for a month and finds their wellbeing at the end to be 7.7. Assume an alpha level of .05. Imagine we know that a treatment actually does have an effect but the researcher concludes there is no effect. 1a. What error has the researcher made? 1b. Why might a researcher make this error? 1c. What is the probability of this error? 1d. How could we decrease this probability?
What is the effect of decreasing the alpha level (for example, from α = .05 to α = .01)? Group of answer choices A. This action increases the likelihood of rejecting H0 and increases the risk of a Type II error. B. This action decreases the likelihood of rejecting H0 and increases the risk of a Type I error. C. This action decreases the likelihood of failing to reject H0 and decreases the risk of a Type I error. D. This action increases the likelihood of failing to reject H0 and increases the risk of a Type II error.

A teacher gives a third grade class of n = 16 a vocabulary test at the beginning of the school year. To evaluate the changes that occur during the year, students are tested again at the end of the year. Their test scores revealed an average improvement of MD = 5.7 points with sD2 = 144. a. Is there a significant difference in students’ test scores over the school year? Use an alpha level of .05. b. please compute Cohen’s d and evaluate it.

A researcher is interested in hamster wheel-running activity during the summer versus the winter. She suspects that either the hamsters will run less during the winter to conserve energy or they will run more to keep warm. She records the activity of n = 25 hamsters during June, July, and August and compares their running-wheel revolutions per hour to the activity of the same hamsters during December, January, and February. The data are collected, and the results show an average difference score of MD - 5.7 and a sum of squares of SS = 2,851.44. What is the sample standard deviation (s) for the D scores? (one decimal)
