1) Those methods involving the collection, presentation, and chara.docx
The document contains a series of multiple choice questions related to descriptive statistics and probability concepts. Specifically, it covers topics such as descriptive statistics, probability distributions, sampling, bias, and inference. The questions are designed to test understanding of key terminology, properties of distributions, and how to apply statistical techniques to answer questions about data and populations.
Program Evaluation Midterm
Researchers are evaluating a new approach to remedial English courses at a community college. They have data on 592 students who took the new two-course option and 5,545 students who took the traditional remedial course. To analyze the impact on degree completion, the researchers can either use statistical adjustments to compare all students or match treatment and control students based on characteristics. It would be worthwhile to obtain additional 10th grade test scores to improve matching and allow for pre-test/post-test analyses, but the scores may not provide sufficient variation or reflect current student abilities.

Grading Rubrics:

Stage I………………………………………………..…………………………… (30%)
A. Select a topic of interest:
Identify the variable under study
a. Topic:
1. Once you have identified your topic, define your variable of interest which will be your topic for undertaking the research. For example, if your topic is the Transportation industry, then you will focus on the profit for that industry, try to identify some factors that will help explain the industry’s profit such as costs of shipment, cost of production, market shares or revenues. Next, try to formulate your title by turning the relationship between profit and one of the explanatory factor in the form of a question that will motive to collect data to solve the problem.
Title: Do revenues and costs influence the profit of the transportation industry for the most recent twenty years?
2. If you are interested in examining the problems facing First Year College Students, then your topic is 1st Year Students.
Title: Does the number of hours of study influence student Grade Point Average?
The relationship between the dependent and independent variables can be known in advance before the data are collected. This pre-relationship is referred to as the theoretical framework.
Reference at least three scholarly articles to understand how each independent variable influences the dependent variable.
1. Article number 1. For example, in the URL search for student performance. A list of articles will show up. Make a brief analysis (3-5 sentences) describing what the author reported about the relationship; positive, or negative. This will be part of your theoretical expectation of the variables before you collect the data.
2. Article 2. Do the same as above
3. Article 3. Do the same as above.
If your topic is first year students, then you will need to identify theoretically all those factors that may explain the variations of the dependent variable. Some explanations are:
Dependent Variable: GPA for the at least twenty-five students.
Independent Variables: In theory, it is argued that as the number of hours studied, student gain more knowledge and confidence in the course material. So, the relationship between GPA and the number of hours studied is expected to be positive (make reference((s) to your articles). Do the same type of expectation for the average distance (in miles) travelled.
B. Creating your data set before you start to write: Data collection.
This data table will be eventually placed as an Appendix
See below the data set in the table showing GPA and Hours Studied, distance travelled for 25 students.
I: GPA: Grade point average over 25 students
II. Variables that may influence GPA are Hours studied, and Distance travelled.

Team-based learning was implemented in an Analysis course to improve student performance and satisfaction. Under the traditional lecture format from 2010-2013, about 24% of students used compensation to pass with a 5, and 15-20% did not take Analysis in their first year. With TBL from 2013-2016, the pass rate increased from 50% to 71% to 60% to 58%. Under TBL, about 10% used compensation. TBL involves individual and team work including writing proofs and peer feedback. Principles of TBL include forming teams with different talents and giving grades for individual and team work. A student survey found 75% read more and half felt TBL helped understand Analysis better.

The document contains a series of multiple choice questions related to descriptive statistics and probability concepts. Specifically, it covers topics such as descriptive statistics, probability distributions, sampling, bias, and inference. The questions are designed to test understanding of key terminology, properties of distributions, and how to apply statistical techniques to answer questions about data and populations.
Program Evaluation Midterm
Researchers are evaluating a new approach to remedial English courses at a community college. They have data on 592 students who took the new two-course option and 5,545 students who took the traditional remedial course. To analyze the impact on degree completion, the researchers can either use statistical adjustments to compare all students or match treatment and control students based on characteristics. It would be worthwhile to obtain additional 10th grade test scores to improve matching and allow for pre-test/post-test analyses, but the scores may not provide sufficient variation or reflect current student abilities.

A. Select a topic of interest:
Identify the variable under study
a. Topic:
1. Once you have identified your topic, define your variable of interest which will be your topic for undertaking the research. For example, if your topic is the Transportation industry, then you will focus on the profit for that industry, try to identify some factors that will help explain the industry’s profit such as costs of shipment, cost of production, market shares or revenues. Next, try to formulate your title by turning the relationship between profit and one of the explanatory factor in the form of a question that will motive to collect data to solve the problem.
Title: Do revenues and costs influence the profit of the transportation industry for the most recent twenty years?
2. If you are interested in examining the problems facing First Year College Students, then your topic is 1st Year Students.
Title: Does the number of hours of study influence student Grade Point Average?
The relationship between the dependent and independent variables can be known in advance before the data are collected. This pre-relationship is referred to as the theoretical framework.
Reference at least three scholarly articles to understand how each independent variable influences the dependent variable.
1. Article number 1. For example, in the URL search for student performance. A list of articles will show up. Make a brief analysis (3-5 sentences) describing what the author reported about the relationship; positive, or negative. This will be part of your theoretical expectation of the variables before you collect the data.
2. Article 2. Do the same as above
3. Article 3. Do the same as above.
If your topic is first year students, then you will need to identify theoretically all those factors that may explain the variations of the dependent variable. Some explanations are:
Dependent Variable: GPA for the at least twenty-five students.
Independent Variables: In theory, it is argued that as the number of hours studied, student gain more knowledge and confidence in the course material. So, the relationship between GPA and the number of hours studied is expected to be positive (make reference((s) to your articles). Do the same type of expectation for the average distance (in miles) travelled.
B. Creating your data set before you start to write: Data collection.
This data table will be eventually placed as an Appendix
See below the data set in the table showing GPA and Hours Studied, distance travelled for 25 students.

BrigitMGeveling.pptx
Team-based learning was implemented in an Analysis course to improve student performance and satisfaction. Under the traditional lecture format from 2010-2013, about 24% of students used compensation to pass with a 5, and 15-20% did not take Analysis in their first year. With TBL from 2013-2016, the pass rate increased from 50% to 71% to 60% to 58%. Under TBL, about 10% used compensation. TBL involves individual and team work including writing proofs and peer feedback. Principles of TBL include forming teams with different talents and giving grades for individual and team work. A student survey found 75% read more and half felt TBL helped understand Analysis better.

Molecular oxygen binds reversibly to the Fe(II)Fe(II) atom in heme.
The heme prosthetic group is entirely buried within myoglobin.
