Question

If a moderator variable moderated the relation between the independent variable and the dependent variable in a study, how does the p-value change? If the p-value when the moderator is present is larger, does that mean the moderator variable weakened or strengthened the relationship between the independent variable and dependent variable?

Answer #1

The p-value changes with the significance of the relationship between dependent and independent variables. Higher p-value indicates weaker relationship and lower p-value indicates stronger relationship. If a moderator variable moderated the relationship between the dependent and independent variable, then the p-value will increase.

If the p-value is larger in presence of the moderator variable, that means the moderator variable weakened the relationship between the independent and dependent variable.

the relationship between dependent variable and independent
variable.

Select two variables, one independent variable and the other the
dependent variable. Explain the cause and effect the relation
between the two. How would you construct the Simple Linear
Regression (quantity of data and how you will measure the results),
and what would you use to validate the equation forecasting an x
value. What will be your expectation of the results of this
investigation?

In controlled comparison research, the observed relationship
between an independent variable (X) and a dependent variable (Y)
may be caused by some other, uncontrolled compositional difference
(Z). So, we always ask, “How else, besides the independent
variable, are the groups I am comparing not the same?” For the
hypothesis below, do the following: (i) Think up a plausible
alternative causal variable. (ii) Describe how this variable might
affect the relationship between the independent variable and the
dependent variable.

A scatter plot shows:
the direction and strength of a relationship between the
independent and dependent variables.
nothing. The line of best fit is what is important.
that there is a linear relationship between the independent and
dependent variables.
how you can predict the dependent variable knowing the
independent variable.

You have estimated the correlation between exposure to
noise (independent variable) and hearing loss (dependent variable)
among factory workers. Both exposure and outcome measures were
collected as continuous variables. The statistical analysis showed
a Pearson r of 0.4 and the correlation between the
two variables was highly significant at p < 0.001.
Question: Can one argue that the
relationship between the investigated exposure and outcome is
causal? why and How likely is the possibility that the results were
a mere chance finding? Why?...

In observational studies, the observed relationship
between an independent and a dependent variable may be caused by
some other, uncontrolled difference. So we always ask, “How else,
besides the independent variable, do the subjects
differ?”
For the two hypotheses below:
a. Think up a plausible alternative casual
variable on which the subjects might differ
b. Describe how this variable might affect the
relationship between the independent variable and the dependent
variable

Regression ____ (b values) indicate how much influence each
independent variable has on the dependent variable.
Regression analysis serves two main purposes: to define the
relationship between variables and to ____ values of the dependent
variable using what we know about the existing correlation between
the variables.
The coefficient of multiple determination, R^2, is interpreted
as the percentage of ____ in the dependent variable that is
explained by the independent variable.

In regression analysis, a higher correlation between the
dependent variable and the independent variable indicates a higher
estimated slope.

In a scientific study:
Select one or more:
a. neither the independent or dependent variable is controlled
by the scientist
b. the dependent variable is controlled by the scientist
c.
both the independent and dependent variable are controlled by
the scientist
d. the independent variable is controlled by the scientist
