Hello,

At your possible convenience, might anyone please kindly answer my
question? Thank you very much.
I got a 95 % confidence interval ranging from 0.000 to 0.004.
I intend to suggest that if the confidence interval doesn't
include zero, the effect of A on B is significantly different from
zero.

Since the confidence interval ranges from "0.000" to 0.004, should
I say that the interval include zero or doesn't include zero?
ps, I got the 95 % confidence interval from bootstrapping method.

Thank you very much.

Please take care

Caroline

Is the statistic discrete or continuous?

Dear Bob,

Thank you very much.
The data were collected from 5-point Likert scale. Some people say
this kind of data are
categorical. Other suggest that this kind of data are continuous.
Might you have any kind solutions to share with me?

If it can only take 5 values, then it's discrete. But I want to know
about the parameter that you have the confidence interval for - that way
we can decide if 0.000 is greater than or less than 0, or equal to 0.

Actually, if it's continuous then a simple solution may be just to add
some more significant figures to your output.

Do you mean a Likert scale 0-5, or -2 to +2?

Hello Caroline,
How many replications did your bootstrap procedure have?
I also wondering how many( or what %) of the replicated estimates were
less than zero?

I am also wondering what does the plot of the replicates look like?
Or can you give us the frequency table?
___________
Frequencies?
-2 |
-1 |
0 |
1 |
2 |


Instead of concluding that zero is/isnt included in the confidence
interval, maybe the plot and the frequency table would be more
interesting?
