The mean is skewed by the outlier and influenced a lot more where as the median would not be changed too much by one value regardless of the value.]]> 2022-03-07 23:18:08 UTC https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082689638 G7 https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082690019
  • Suppose you are doing the Evaluate Quiz, and you see someone post answers on Ed or Facebook. What should you do?
    • Report it to the teacher 
    Finish that quiz on my own 

    • A friend offers you their Project 2 from last year. What should you do?
    Reject the offer from my friend, and do the project on my own, remind him this is inappropriate. This will count as cheating.

What should you do? Reply to the person that we are not supposed to do so,  do not look at the answer, and inform a teacher.

    A friend offers you their Project 2 from last year. What should you do? Remind him that it is not appropriate and refuse and once again tell a teacher/tutor.]]>     2022-03-07 23:19:19 UTC https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082690747     G3 https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082691403 if you are offered someone's Project 2 from last year = Decline. It would be morally wrong to take it. If you got caught you would get a 0. You learn nothing because you skipped the process of doing the assignment and you'll then struggle in later assignments. Intellectual theft. 

    Looking at Ed for answers = Don't use the answers. Not exercising your brain to workout answers, you won't learn from taking the answers from someone else. Report the person who has posted the answers to the unit co-ordinator. This is a form of cheating and will result in a penalty. ]]>     2022-03-07 23:20:02 UTC https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082691403     G5 https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082693904 q1:Ignore the answers and report it the teachers

One outlier could influence the mean change, especially the outliers are the biggest and smallest.]]> 2022-03-07 23:24:25 UTC https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082695408 G11 https://padlet.com/siye43991/vjwwchm8fp9aod78/wish/2082696711 The median is said to be robust and is a good summary for skewed data as it is not affected by outliers.

    Mean is equal to sum of data/size of data, so extreme data is gonna affect the value of the mean.

Thus, represents are more accurate representation of the data set.
