[Yr11 Information Technology] yr11it Digest, Vol 129, Issue 3

Thu Dec 10 12:19:59 AEDT 2015

Hi Mark,

One possible interpretation:

  *   correctness means that the correct data items are collected/used to generate the required information
  *   accuracy means that the values of the (correctly chosen) data items are …. well, accurate!

Eg - When calculating student attendance it would be

  *   incorrect to only count days when students were in the classroom since excursions, incursions etc should also be included
  *   inaccurate if someone has erroneously marked the student present, or absent

Your thoughts????

Regards,

U1O3 KK5 - 'factors affecting the integrity of data, such as correctness,
reasonableness and accuracy'

Your challenge for today is: Work out a way to explain the difference
between "correctness" and "accuracy" to a year 11 student.  The prize is 50
brownie points.

Yes, I realise the terms are only given as examples in the study design,
and are not made mandatory by the word 'including', but I'm interested if
anyone can clearly tease out the difference between two terms usually
considered synonymous by everyone except scientists.

The only thing I can suggest is that "accuracy" means "correctness" (free
from error) but also has an whiff of 'precision' about it too...

e.g. storing Pi as "3.14" may be *correct*, but not as *accurate* as
"3.14159"

Good luck.

Hi All,

A similar question was raised during my session at the DLTV in-service and in a nut shell (I can?t remember the excellent example that my audience provided):

I can cut a piece of wood to be 2003mm in length (accuracy), but if I should have cut a piece of metal it would not be correct.

Like in maths; mark for correct answer but if not to the correct decimal places then lose a mark.
Or lose all marks sometimes if correct but not accurate.

Hi everyone,

I am looking at Chapter 2 for VCE Computing, and need to know if anyone has some great online Infographic making software that is free and makes good products.

I know about Infogram https://infogr.am/  and  Easelly http://www.easel.ly/

BUT

are there other ones like this, that are good to use for Y11 VCE Computing Unit 1 Outcome 1 ?

I have also found some videos:

Video About Infographics

https://www.youtube.com/watch?v=VQbFX2QzbOI

Animated Infographics are great like this one of the earth past and future

https://www.youtube.com/watch?v=2XkV6IpV2Y0

and this one from "The Infographics Show" YouTube Channel on Obesity:

https://www.youtube.com/watch?v=IkoC3HZwe7Q

The Infographics Show channel on YouTube also has good presentations on water, and fast foods, and lots of other interesting topics.

Enjoy,
