Question

. In terms of the mean and standard deviation:
- What does it mean to say that a particular value of x has a standard score of +1.5?
- What does it mean to say that a particular value of x has a z-score of -2.6?
Please show all work.

Answer 1

If a value of x has a standard score of 1.5, this means that x is 1.5 standard deviations above the mean.

The mean divides a distribution in half. Half the values are above the mean and half are below the mean.

I'll let you try the second question on your own.

I hope this helps.

Answer 2

I really don't understand statistics and am not sure if I am trying to make it harder than it needs to be, but I am lost!

Answer 3

Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
