So first of all, you have to talk about what the independent variable was.
00:05
And the independent variable is the degree of modernization.
00:17
And it has three levels, and that was the low, the medium, and the high.
00:24
And the dependent variable is the annual suicide rate per 100 ,000 people.
00:40
Now part b says that we need to plot a scatter plot by, oops i'm sorry, looking at the wrong table.
00:54
We need to in part b create a source table with degrees of freedom, sum of squares, and the mean square.
01:00
And so why don't i start out actually first of all with the assumptions.
01:05
We're going to assume that the mean for low is equal to the mean suicide rate, or medium is equal to that for high.
01:13
And alternately, they are not all equal.
01:19
Not all means are equal.
01:26
And so here will be our table.
01:29
And we have our factor, which is we know the degree of modernization will have the air.
01:36
And we want our degrees of freedom, the sum of squares, and the mean squares.
01:41
I have my data in a list, and i'm going to go to stat and tests and anova on list 1, list 2, list 3.
01:50
And our degrees of freedom is 2 for the factor.
01:54
Our sum of squares is 259 .2.
01:58
Dividing those, we have 129 .6 for the mean square.
02:02
For the air, we have 10 degrees of freedom, 158 .8, and then that quotient gives us that 15 .88...
