Statistics Partner Projects

  • The language one uses when asking a statistics question may cause the results to differ. You can encourage the results of the survey by asking the question in various strategic and bias ways.
  • Poll by population is more accurate that randomly.
    Example of a poll taken by sample: 4 out of 5 Olympic runners recommend this shoe…
    Example of a poll taken by population: 542 out of 659 of all Olympic runners recommend this shoe…
  • Convenience Sample: A convenience sample is choosing people who are easy to access. Example: I am writing this answer in Math class, and if I decided to do a poll right now, and I only included the people in this classroom, this hypothetical poll would be by Convenience Sample. The benefit of this would be that it’s one of the easiest, because you choose the people that are closest to you, and this is one of the fastest sampling methods.Random Sample: A random sample is choosing random people of the population. Example: If I made a poll on the internet, and the first 1000 people who go on any social media website are forced to take the poll, that would be a Random Sample. A random sample is most non bias way of data analysis, because you are not choosing the people who take the poll, it is random.Stratified Sample: A stratified sample is a group derived from a set percentage of other multiple groups formed from the whole population. Example: There are ≈7 billion people on earth, if we divided that in to 4 group we’d have 1.75 billion in each group, and then we took a percentage out of each group, let’s say 25% then those 437.5 million x4 = 1.75 billion, and if we polled these people, this would be a poll by Stratified Sample. The benefit of this is that you’re practically including the whole population, but it is easier because you don’t have to include everyone.Systematic Sample: Choosing people after each set of intervals. Let’s say we have the whole population of Port Coquitlam, and we chose every 3 person from the long line, that would be a Systematic Sample. This is also really easy to do, because you only have to poll a percentage of the population.

    Voluntary Response Sample: A sample that allows the whole population to participate. An example of this would be presidential elections, because they include the whole population of a certain area. This is definitely one of the best kinds of samples because it includes everyone.

    Choosing an inappropriate sampling method is common among many companies, most commonly, companies who are trying to sell you something, or convince you to support their opinion. By choosing an inappropriate sampling method you can make your numbers seem way better than they are. For example, you could go in to a poetry club, and poll the members by Convenience Sample, this way, most of them or all of them will say that they like poetry.

  • Theoretical Probability is what is expected to happen based on the possible outcomes.
    Experimental Probability is the result of an experiment or simulation after a large number of times.Theoretical is expecting something to happen, while Experimental is actually doing the tests.
  • Some companies may say that their product is the most durable, but there is no way to really know because your not going to buy every other companies’ products too just to test out their durability.

    Some tooth paste companies or tooth brush companies may say that their products are the best products to get rid of plaque, but an average consumer can’t really tell if their saying the truth or not.

    Some news channels may show you statistics that would help them convince of believing their opinion is the best opinion to have, by showing you numbers but the polls showing you something that’s really zoomed in so you can’t actually see the whole statistic chart.

Skype Chat with Charis Walko

Skype Chat with Charis Walko

On January 15th, 2016, Mr. Robinson set up a Skype call with Charis Walko so the class could ask questions about Embryonic Stem Cells and other subjects involving Stem Cell research. The class was set up in pairs. My partner was Michael land.

Our question was: Can you share what you are currently working on ?

Her answer was: I am currently working with a company that specializes with Stem Cell Research, and I make a chemical that tells the stem cell what kind of stem cell it should be.

[Me (Botond Diosy) asking our question to Charis.]

Other questions:

What is your favorite thing about your job?
Discovering an understand new stuff that no one else has seen before.

How is your work contributing to modern day medicine?
We can make organs, that someday will be able to be transplanted in to a human.

I really liked this experience, I learned lots of new things about stem cells. And in my opinion this turned out better than the Skype chat with Tanya Harrison.

My Mutation Story

My Mutation Story

Severe Combined Immunodeficiency Disorder (SCID) is a disorder in which individuals are born without an effective immune system.

I am a mutated gene called SCIDX1, and I am located on the X chromosome, because I am mutated I disturb the development of “T cells” and “B cells”. T cells participate in immune response. B cells produce antibodies. Therefore, they’re really important for my host’s everyday life. I the gene, hold codes to make a protein that is used to build a receptor called IL2RG (interleukin-2 receptor). These receptors are located in the plasma membrane of immune cells. The receptors’ job is to allow two types of immune cells, T cells and B cells, to communicate. When I was mutated, the receptors couldn’t form and were absent from immune cells. As a result the immune cells can’t communicate with one another about bacteria and other malicious microorganisms. T cells and B cells will try to fight off the infection but there are too few of them to do so.

If my host was a female, which is rare occurrence, there would be a way smaller chance my host having SCID because females have two X chromosomes. The X chromosome is what a mutated gene like me is located on at the early stages of the host’s life, it was more likely for me to be inherited in to a male host because they can’t compensate for me like some females can, (females have two X chromosomes which plays a big part). P.S. Even if a female host doesn’t develop the disorder, they can still pass it on to their children.

My host is age 12, he lives in a physical plastic bubble, and it has a loud and annoying compressors attached to it, everything is sterilized before entering his bubble, clothes, food, etc. NASA even made him a “bubble suit” so he could explore the world with minimum risk of infection. But that was 12 years ago, tomorrow is a big day, tomorrow my host is going to receive a bone narrow transplant from his sister that will hopefully cure him of his disease.

[After the bone narrow transplant]

My host’s sister’s bone narrow contained traces of dormant virus, which resulted in my host’s death.

My host was David Vetter.

Part 2

  1. SCID, “What causes SCID?”, “How do people with SCID live?”.
  2. I used Open Office writer to write the story, and “Google” to research the desease.
  3. I researched websites through “Google” and summarized what I learned.

    These are the links to the websites I used to learn about the disease.

    http://learn.genetics.utah.edu/content/disorders/singlegene/scid/

    http://io9.gizmodo.com/10-unusual-genetic-mutations-in-humans-470843733

    https://en.wikipedia.org/wiki/Severe_combined_immunodeficiency

    https://en.wikipedia.org/wiki/David_Vetter

  4. I read the same information on multiple websites to verify the information.
  5. The process wasn’t easy, I didn’t know how I would implement a story about a gene mutation and the gene’s host, but I think it came together pretty well. I could have done a better job with the story, and maybe explaining things a little more in depth, but I don’t know how to write a story that had lots of facts in it.

Skype Chat Blog Response

“Is it possible to get a rover back from mars?” my lab partner Michael Land asked Tanya Harrison a Planetary Scientist and Geologist with Centre for Planetary Science and Space Exploration (CPSX), on Wednesday, December 9th of 2015. (Tanya Harrison is a student from Ontario, Canada working on her PhD right now.)

Mr.Robinson set up a Skype call with Tanya so the class of Grade 9 Science from Riverside Secondary School could ask her some questions about the rover “Opportunity” and other topics related to space.

Michael Land talking to Tanya Harrison.

“Is it possible to get a rover back from mars?” Michael Land asked Tanya Harrison, she answered with; “We don’t have the technology to make rockets powerful enough to fly other rockets that would bring back the rover, however, we do have the technology to bring back rock samples from mars to earth, with is a mission NASA is currently working on.”

How I felt about this project:

I’m the kind of person who’ll read articles about space for hours everyday, I am really interested in the topic of the vast unknown, so it was really cool that someone of the rank of Tanya answered our interesting questions.

Currents from the Kitchen

Currents from the Kitchen

Our predictions were that a lemon would produce the most charge.

We couldn’t find a lemon so we did our experiment with a lime and it had great results.

We were able to generate 1-volt. The shorter the copper wire was the stronger voltage we got.

The strongest charge we managed to produce was 0.8v – 0.1v (v = volts).

Lab Requirements:

A Fruit or Vegetable

A Copper Wire

Zinc

2 Crocodile Wires

Volt Meter

fruit voltage experiment2

Experiment done by (Boti and Jennifer).

Q1. What kind of circuit will produce electron flow in your fruit/vegetable cell?

A linear wire circuit using a fruit battery(lemon, copper, zinc).

Q2. If your bulb doesn’t glow, how can you find out if electrons are flowing?

Using a voltage meter, you can see the strength electricity in the measurement called volts.

Q3. If your bulb doesn’t glow, why not?

Because the voltage is not strong enough to power the light bulb.

Q4. How can we modify our experiment to improve our results?

Connecting more fruits to each other in a parallel system.

Q5. What is causing electrons to flow in this experiment?

The chemicals release electrons in the hopes that they will find protons.

Q6. How can I use this in my everyday life?

You could use it in emergency situations, but it wouldn’t be convenient in “everyday life”.

Q7. Is this the next “big thing” in clean energy?

No, this isn’t exactly useful in any way, for everyday use. It’s only useful for emergencies in my opinion.
