Original Week 4 Post:

ALEKS Scavenger Hunt:

This week you’ll demonstrate your problem-solving skills by sharing how data can help you solve problems in ALEKS.

First, post a screenshot of one of your unsolved questions that you have worked on or are working on in ALEKS. Then add a comment on how data can help to answer the question or how this type of data can help you to make data driven decisions.

Next, pick a question submitted by someone else in your class that you have solved, and leave a comment about the data-driven strategy or tool you used to reach a solution.

Be sure to respond to at least one of your classmates’ posts.

Hint: There are some great tips for solving each problem in the videos located in ALEKS above the calculator labeled Instructor Resources. You can also ask your instructor if you have any questions.

Charts and graphs are often used to present statistics in newspapers, magazines, books, and various online articles. There are pros and cons to using these types of visual representations.

Describe one pro and one con for using a graph or chart. Then, share an example of a time when a data visualization (like a graph or chart) changed your mind about something or gave you a deeper understanding of a topic or current event.

Be sure to respond to at least one of your classmates’ posts.

One pro and con about using a graph chart is a few things a pro is the graph chart can help you display a lot of informationis an easy to understand format. And one of the disadvantages is there are many different types of formats that are used by chart and graphs and it is hard to distinguish. Them sometimes and another advantage is summarizing a large dataset in visual form so there are many forms of data you can include in the graph that ensures an accurate. Amount of data and the main point of a graph chart and the intial premise of a graph chart is to put as much data in the graph.

This week you’ll get a headstart on your Week 9 Assignment – Data Analysis and Visualization by searching for and summarizing a newspaper article that highlights a real-world problem that could be solved through statistical data.

To successfully complete your discussion post, include the following:

The title of the article, the date it was published, and a link to the article.

A bullet-pointed summary of the purpose of the article and the problem it is trying to solve.

A brief explanation of how the article uses descriptive statistics to communicate information, conclusions, or solutions found in the study.

Be sure to respond to at least one of your classmates’ posts.

INSTRUCTIONS:

Note: The instructions for this discussion are the same as Step 1 in your Week 9 Assignment.

To begin, visit one of the following newspapers’ websites: USA Today, New York Times, Wall Street Journal, or Washington Post. Select an article that uses statistical data related to a current event, your major, your current field, or a future career goal. The chosen article must have a publication date during this quarter.

Example topics may include:

Elections/exit polls

Award shows (Oscars/Emmys/Grammys)

Sports

Economy/job market

Gender equality

The article should use one or more of the following categories of descriptive statistics:

Measures of Frequency – Counting Rules, Percent, Frequency, Frequency Distributions

Measures of Central Tendency – Mean, Median, Mode

Measures of Dispersion or Variation – Range, Variance, Standard Deviation

Measures of Position – Percentile, Quartiles

Note: Once you navigate to a publication’s website, it may be easiest to do a search with a statistics-related word (ex: standard deviation).

EXAMPLES:

Explore below for examples of how the different statistical categories above were used in recent newspaper articles:

Example 1:  Statistical Category: Measures of Frequency – Counting Rules, Percent, Frequency, Frequency Distributions.

Title: Weekly Mortgage Refinance Applications Spike 15% as Interest Rates Plunge to Lowest in Nearly 4 Years (February 5th, 2020).

Statistical Data: The percentages in the quote below are measures of frequency.

“The average contract interest rate for 30-year fixed-rate mortgages with conforming loan balances (\$510,400 or less) decreased to 3.71% from 3.81%, with points remaining unchanged at 0.28 (including the origination fee) for loans with a 20% down payment.”

Example 2:  Statistical Category: Measures of Central Tendency – Mean, Median, Mode.

Title: Here’s the Average American’s Credit Card Debt – And How Much It Costs Them (February 23rd, 2020).

Statistical Data: “The average American has \$6,194 in credit card debt at an average interest rate of 16.88%.”

Example 3:  Statistical Category: Measures of Dispersion or Variation – Range, Variance, Standard Deviation.

Title: Franchises that Work Out: Many of the Hottest US Businesses to Franchise Involve Fitness (February 17th, 2020).

Statistical Data: This is an example of measures of dispersion because it shares a range: “Estimated franchise startup cost: \$2,000 – \$20,000.”

Example 4: Statistical Category: Measures of Position – Percentile, Quartiles.

Title: The 4 Main Grad School Admissions Exams, in a Nutshell (March 30th, 2017).

Statistical Data:

“Score range: Between 130 to 170 for Verbal Reasoning, with 150 being the 50th percentile; between 130 to 170 for Quantitative Reasoning, with 152 being the 50th percentile; and between 0 to 6 for Analytical Writing, with 3.5 being the 50th percentile.”

Be sure to respond to at least one of your classmates’ posts.
