Misleading stats

In my math class, we are studying how statistics can be misleading.  We were assigned to find a current day headline, graph, media story that uses statistics in a misleading manner and explain why it is misleading.

This one has the correct figures, but that big headline makes you think that 5.3% of children get spinal cord injuries making it very fear based on parents.

The real figure is about .0000003% (based on 2000 injuries per year out of a population of around 74,000,000.

Fox News Misleading Graphs.

Fox News showed this chart of what would happen if the Bush tax cuts expired. The scale starts at 34 to make the stats look way larger than they actually are.

Misleading Statistics Examples in Advertising.

80% of dentists will recommend everything.

Misleading statistics examples 2

Colgate ’s claim that 80% of dentists recommended the brand. Consumers were led to believe that 80% of dentists recommended Colgate while 20% recommended other brands. It turns out that when dentists were surveyed, they could choose several brands — not just one. So other brands could be just as popular as Colgate. This completely misleading statistic was banned by the Advertising Standards Authority.

Thoughts on Data Analysis 2018

what role do statistics have on our society?

In my opinion, statistics play a major role in our society, it gives people more of a choice. People don’t always get choice and when they do  I think that they should use it to their advantage. People can get very angry when they don’t feel heard and that can result in many consequences. In our society people nowadays spend most of their time on technology and don’t often give things a second thought. with statistics, people have the option to make decisions for themselves and the community. Although, there are some negative things about statistics, people who don’t vote or make an impact often make the survey or statistics inaccurate if the voting doesn’t have proper standards.

What have I learned from the article about the importance of statistics in our society?

statistics play a huge role because they provide solid information for the person receiving them, they can give solid information for the person’s research. Data provides the opportunity to back up information for example evidence. Without proper data, people are forced to make decisions and choices by making educated guesses based on the case. Which might result in consequences that affect other people in negative ways.

There are also some problems with statistics;

This may not be the questioner’s fault but sometimes the vote and or poll can be represented in an incorrect matter. People can make mistakes and errors in their question causing the results to be inaccurate.

Here are some factor’s

Bias                             – does the question show a preference for a specific product?

 

Use of Language         – Is the question presented in such a way that people understand what is being

asked?

 

Ethics                          – Does the question refer to inappropriate behaviour? Ethics involves judgement of

right or wrong. For example, cheating on a test is considered wrong.

 

Cost                             – Does the cost of the study outweigh the benefits?

 

Time and Timing        – Does the time the data was collected influence the results? Is the timing of the

survey appropriate?

 

Privacy                        – Do people have the right to refuse to answer? Are the responses kept confidential?

 

Cultural Sensitivity     – Might the question offend people from different cultural groups?

  86% of statistics are made up on the spot, you know – the remaining 24% is mathematically flawed.

11.1 factors influencing Data collection

In my math class, we are learning about how factors can affect data when doing a poll.

Should Christmas break be called winter break to avoid hurting the feelings of people who are different?

this question has a couple of influences, primarily this question has a cultural factor and it doesn’t respect the people who don’t celebrate Christmas, even though the question should be making a rightful change.

  • Cultural Sensitivity

this question also has an ethical violation, it isn’t right to make an assumption that people who don’t celebrate Christmas is wrong and or different.

  • Ethics

this question should be reworded to;

In your opinion, should Christmas break be changed to winter break? because of the large number of people who don’t celebrate christmas.

my digital footprint

1.) How might your digital footprint affect your future opportunities?

My digital footprint could affect many things, but one of the biggest things is that it can effect is your future. for example if you were applying for a job or applying for an entrance into a post secondary school, they could research your history and things you post online. If they find something negative they probably wouldn’t hire or accept you. if you had a positive digital footprint it could definitely improve you chances of them accepting or hiring you.

2.)Describe at least three strategies that you can use to keep your digital footprint appropriate and safe.

Make sure whatever you post or share is something that is important and doesn’t present you in a negative way. If you have to think about it too much you probably shouldn’t post it.

Don’t share your passwords with anyone, because even if you think its funny if your friend post’s something it might get you in trouble.

another way to make sure that you are safe online is if you always remember that what you are posting its available for everyone to see and even if you delete it its still there.

3.)What information did you learn that you would pass on to other students? How would you go about telling them.

It’s always funny when a friend sends a you a funny text but, is it really funny when that friend post’s it on your account and you get in trouble for it? Future employers and schools always research you digital foot print and if it presents you in a negative way the chances of them accepting or hiring you are quite slim. But it is a great idea to have a positive footprint because it’s impressive to future employers and future schools when you have a positive footprint. It sets you apart from others. Always make sure you think before you post or follow someone.
