00:01 Hi, i'm david and i'm here to help me and change your question.

00:03 Now let me bring up your question here.

00:06 In this question here we have the multiple choices for the three questions.

00:10 On the number eight, we're discussing about the shaft on the distribution.

00:15 Let me remind you that when we talk about the several distribution, it will have the three times the shaft here, where we have the one that will be left skilled, and then the one that will be the right skilled.

00:41 And then we will have the one that will be the symmetry here.

00:50 And then for those three types under distribution shape here, we will have the different mean median and the mode.

00:58 And when we change in room from one to the others, on three of them will be affected and they will change in on the time.

01:04 Therefore the answer for this question here, which measures of central tendency is affected by the shaft? and the answer will be on three of them.

01:14 Now the second one, the value of the lowest score in distribution is changed from x equals 20 to the x equal to 30 and then which measures of center tendency is all certain to be changed.

01:33 So when we change the value of one score and then we will see certainly that the mean will be changed.

01:40 That could be the first one for sure.

01:41 And for the median, we will see this one because it will be the lowest score.

01:48 It will be changing from the x -evity 20 to the x -goat -30, they will make change the median.

01:57 And then we will see that it depends on how the lower score and the value on the 30 will be location...
