The increase in students taking college courses is due to:
1. Convienence
2. Cost
3. Savings (gas, transportation, parking, housing, etc...)
4. Can continue working
5. Increase in non-traditional students
6. Technology

By the year 2020 the percentage of college students taking on-line classes will increase to 80%.

Given the average increase over the past 6 years, we feel the increase will be about 50% of the students will be taking online courses.

By analysis of the data presented from USA Today, I infered that by the year 2020 approximately 46.62% of students will be taking on-line courses. I reached this conclusion by creating a scatter plot and finding my line of best fit. Then I made inferences on that data to conclude that 46.62% of students will be taking on line courses. With this information, I then wanted to see if my analysis was realistic, I do not believe that it is, I believe that the percentage will be much higher by the year 2020.

By 2020, 54.8% of students will have taken online classes. To justify the answer, we used USA Today Snapshot graph. First we found the average percent increase over the last four years to be 2.5%. To find out the percentage in 2020, we took 2020 minus 2006 to get 14 years difference. To find the percentage one must take 14 times 2.5% to equal 35.0%. Take 35.0% plus 19.8% (the percentage in 2006) equals 54.8% in 2020.

Based on data the increase in students taking on-line courses will continue to rise at 1 to 2 percent each year. By 2020 the number of students participating in on-line courses would be approximately 45%. The reasons behind this trend is more there are more students attending college who are working full-time, who have families, and live in rural communities away from universities. On-line courses allow a diversse group of people to attend college while staying at home.

More computers available, more convenient, more people trying to multitask,more courses offered and more degrees offered, more versatility in course offerings, 50% of people will take on line courses by the year 2020. We think there was an invrease of 10% over the 5 year period and another 14 years would produce 50%.

The trend of students taking online classes is increasing. We would expect the percentage of students taking online courses to be approximately 50. This is based on making the assumption that the current trend will be maintained, and at a similar rate of change. The average percent of increase in the time provided in the chart is a little above two percent per year, and given that over a fourteen year period the percent increase should be approximately 30%. The latest percentage give was very close to 20%, thus a 30% gain would produce a total percentage of approximately 50% by the year 2020.

convience,the advancement of technology, expense, time.

by the line of best fit, with an increase of 10% every 5 years, the prediction of the number of people taking college courses should be approximately 50%.

The change has averaged about 2.5% per year so the projection by 2020 is around 55%

More people are taking courses online because of higher gas prices, more people are going back seeking alternative certifications to improve employment options, the time constraints of Americans' busy lifestyles, and because universities are beginning to offer classes that are ONLY offered online.

In the year 2020, we predict that 37% of college student will be taking classes online. The number of online students will increase becasue of more high-speed internet customers and because of universities seeking to cut costs. The increase in online students will continue to be limited; however, by the tradition high school seniors seeking the "college experience."

There are more quality online courses available because of technological advances and instructor savvy with technology.
The convenience is attractive to the consumer. Colleges are encouraging online courses because it is cost effective and it attracts more students.
By 2020, the percentage of students taking online classes will be high, especially in the industrialized nations. From 2002 until 2006, the percentage of students taking online courses doubled. The advances in technology will allow online classes to be the norm. Classrooms at that time should look different from today.

I believe that the percentage of internet users by the year 2020 will be approximatley 54.7%. By calculating the rate of change, I found that the amount of internet users per year was about 10 percentage points (rate) for every four years. I then created a linear function using the slope of 10 percentage points to every 4 years and then the y-intercept was the initial value of 9.7 percent at 2002. y = (10/4)x + 9.7 where y = Percent of internet users and x is the number of years since 2002. I substituted 18 years in for x. and found it to be 54.7%

The increase in the percentage of students taking online courses can likely be explained by several factors. These include greater numbers of nontraditional students taking college courses. The draw for these students is the convenience for those with job and family responsibilities. Another factor would be budget cuts at the university level. A traditional on-site class might have 30 participants whereas an online course could easily have 100. Finally, access to faster technology has increased over the years thereby allowing for more students to use the online option.

During the 5 years shown in the chart, there was an average increase of 2.61% per year. If the percentages continue to change at the same rate, by 2020, I would predict that approximately 57% of students will be taking online courses.

The increase in the number of college courses being taken online is due to the number of students who work, support a family, or both.

The need for an education is becoming more important as the years progress and we are seeing more non-traditional students in our colleges today.

After analyzing the bar graph over the last five years we believe that the number of students will continue to increase but will likely begin to plateau after several years. The number of people possessing the ability to learn independently without individualized face-to-face instruction are not the majority,but indeed are the minority.

Therefore we predict that the percentage of students taking online college courses will be in the range of 35-40% by the year 2020.

Over the past several years there has been a great increase in the number of non-traditional students seeking college degrees. Online courses are more "user-friendly" to non-traditional students, offering more flexibility for these students. In addition to taking college classes, non traditional students have many family and career obligations that keep them attending traditional college classes.
Based on the data provided, the percentage of students taking online courses doubled between 2002 and 2006. If this trend continues, it is very possible that 50% of students will be taking online college courses by 2020. This is due to the fact that online courses are very convenient and allow the student more flexibility in completing assignments.

The increase in the percentage of students taking only classes is affected by many factors, including: advances in technology, family support, job competition, affordable technology

An estimated 48% of students will participate in online college courses. This estimate is based on the steady increse yearly that has been approximately 2% each year.

In the age of the internet and the iPhone, the percentage of students who choose to take online courses has begun to increase dramatically. An explanation of why more students are choosing to take online courses would include the following reasons:
• Efficient use of time for students – students with families, jobs
• Interactive – must take an active role in your own education
• Travel issues – fuel costs, insurance
• More current – up to date issues
• Encourages application based learning – including technology-based learning, use of websites, tools, 21st century communication tools
• High level of engagement and collaboration
• Cost-effective for universities
• No overhead (bricks and mortar), one professor to teach thousands

All of the above results in lower tuition for the students, in theory.

By the year 2020, close to one-third (over 30%) of students will be taking online classes. The constant and ever-present threat of fuel prices increasing along with the non-traditional student enrollees increasing will continue this trend toward to more students taking online courses.

Online course enrollment is on the rise. Several factors may contribute to the 2.5% average increase in enrollment from 2002 to 2006. Online courses offer benefits to both the universities and their students. Universities may find online courses more profitable because more students can be served with less faculty and facilities are virtual. Students juggling responsibilities among jobs, families, and schooling find online courses attractive because it is convenient, cost effective, and can be tailored to their individual schedules. Based on the current trend, by the year 2020 approximately 55% of the college students could be enrolled in online course.

The increase in students taking online college courses occurs for many reasons. Many people find online classes to be convenient because they can complete assignments from their homes on their schedule. It is also a money-saver because it cuts down on normal costs that are incurred from traveling to colleges to take classes.

By the year 2020, the percentage of students taking online courses will increase. However, looking at the last two years from the USA Today graph, it seems that there is a possibility that the usage of online classes might level off. You could figure the mathematics of the "general" increase over the four year span, but it is more likely that the usage will level off or increase a little slower after 2006.

A good estimate for the percentage of students taking online classes in 2020 is between 35% and 45%, with most students taking regular college courses mixed in with online classes. This is because of the lack of relationships that can be created with online classes, and that is a huge part of a college experience. While there will be some people who will want the classes without the college experience, it is far more likely that online classes will NEVER be the prevailing type of class taken by college students.
