Is 20 points were scored in the next game which measure of central tendency would change the most?

No, both televisions are not similar.

Aspect ration 12:9 is similar to 4:3

Step-by-step explanation:

Lets consider it this way.

Aspect ration can be defined as a ratio of width to height.

For a television with aspect ratio 4:3

which means that the width will always be 33% greater than the height, which will result in a boxy image.

For a television with aspect ratio 16:9

16 - 9 = 7

which means that the width will be 78% greater than the height, which will result in a rectangular image.

Hence, both are not the same.

Exact similar dimension to that of 4:3 can be 12:9 because in both, width is 33% greater than height
