Week 6

In Tuesday, we talked about differentiation between variability, variation and variance
Variability: değişebilirlik : the level of variation in data set : uncountable : there is no such value

Variation: değişkenlik : amount of the change

Variance: değişim : change from a situation to situation

They sound so similar but there are differences between them.

And we talked about statistical habits of mind. The steps are: 

1.always consider the content of data

2.ensure the best measure for and describe variation

3. anticipate look for and describe variation

4. attend the sampling issues: you need the sample which represent the population as good as it can

5. embrace the uncertainty but build confidence in interpretation: do your best the confidence in your interpretation

6. use several visual and numerical representation for making sense of data: graph etc. Make sense it for others

7. be a skeptic throughout the investigation

In thursday we start to learn about CODAP I think its funny and useful tools for the students and teachers. I am very happy to learn something about CODAP.
