Your younger brother, a fourth form practical geography student wishes to test whether there could be some relationship between annual visits to a local market by all residents surrounding that market. After a well-designed field study he obtains the following figures:
Number of visits per year
21
13
19
18
17
17
14
20
10
11
Residence distance from market (KM)
1.0
2.0
3.0
4.0
5.0
6.0
7.0
8.0
9.0
10.0
From the information above, what is the dependent variable and what is the explanatory variable?
Using (i) above, obtain the regression equation of Yi on Xi. Hence, estimate the residence distance from the market (in KM) if the number of visits are 16 visits
Sketch your results in (ii) above. What conclusion can you draw from your sketch?
I'm a bit confused on how to "discuss the relationship" for part a and "
Interpret" for part c.
I also want to know how to start part E; which test (if any) for I need to use?
You have the following two data points for a process undergoing learning: Y3 = 50 and Y7 = 35 What is the best equation to use for prediction?
Group of answer choices
Yx = 84.2 x-0.2324
Yx = 77.6 x-0.5323
Yx = 79.4 x-0.4210
Yx = 80.7 x-0.3365

Next run the appropriate analyses through JAMOVI and report your findings in APA. Research scenario 1: In a study looking at undergraduate students' perceptions of sense of community at their university, a researcher hypothesizes that the farther away students live from campus (in miles), the less they feel they are part of the university community. The researcher collected data for the following two variables – miles from campus and part of community (continuous rating scale from 1-10 of how much they felt part of the university community).arrow_forward5arrow_forward

- Take a moment to address the following scenario. Imagine that two women of similar sociocultural back-grounds, a 21-year-old and a 60-year-old, both express their desired goals as “I want to lose 20 pounds [9 kg] in the next three months.” What thoughts come to mind? What questions would you want to ask of each woman? What motiva-tions might you assume? The one variable presented here is age. What are the assumptions you have about age and weight loss? Our assumptions are that given the aging process and the phases of human development, weight loss might mean different things to these two women. These meanings, along with the women’s personalities, will color their engagement in and approach to coach-ing as they seek to achieve the same goal.

One study examined survivors' recall of the sinking of the ship Titanic (Riniolo, Koledin, Drakulic, & Payne, 2003). The researchers reviewed the transcripts of survivors' testimony at governmental hearings (www.titanicinquiry.org) to see whether they testified that the ship was intact or breaking apart during the ship's final plunge (it was in fact breaking apart). To test for eyewitness accuracy, testimony of 20 survivors was examined to see if there was an equal likelihood of survivors saying the ship was intact or breaking apart.
