Question

which of the following are true about standard units? assume we have converted an array of data into standard units using the function above. (5 points) the unit of all our data when converted into standard units is the same as the unit of the original data. the sum of all our data when converted into standard units is 0. the standard deviation of all our data when converted into standard units is 1. adding a constant, c, to our original data has no impact on the resultant data when converted to standard units. multiplying our original data by a constant, c, has no impact on the resultant data when converted to standard units. assign array 1 2 to an array of your selections, in increasing numerical order. for example, if you wanted to select options 1, 3, and 5, you would assign array 1 2 to make array(1, 3, 5).

Answer 1

It is to be noted that all the following are true about standard units. Here is why it is so.

1. Is true because Standard units remove the original unit, making it unitless for easy comparison.

2. Is true because when data is in standard units, the sum is always 0, maintaining balance.

3. Is true because standard deviation in standard units is always 1, providing a consistent scale.

4. Is true because adding a constant to original data doesn't affect the unitless nature of standard units.

5. Is true because multiplying original data by a constant maintains the ratio, leaving standard units unchanged.

So, it is to be noted that all the selections, in increasing numerical order, would be array (1, 2, 3, 4, 5) as all the statements are true when data is converted into standard units.
