Easy
The video is about ___ Test step by step problem solving
Kolmogorov Smirnov / KS
What is step 2?
Find the frequency and cumulative frequency of each data point (ECDF)
Where do we get the critical value?
In KS table/ Kolmogorov Smirnov table
What is the first step?
STEP 1: State the hypothesis
In which column of the table in step 2 would we find the ECDF?
Cumulative frequency column
If D value < D alpha, what do we conclude?
We accept the null hypothesis
In problem 1 and 2, what does n symbolizes?
Sample size
In step 2, column 1 or “x” column, where did we get the x values?
Sample data
State 1 of the decision rules
If D-value is less than the D-alpha, accept the null hypothesis
What does the alternative hypothesis states?
The sample comes from a different distribution
In problem 1, what is the frequency of the sample data of 5?
2
What are we going to use in the computed D-values?
Maximum D value
What does null hypothesis states?
The sample does not come from a different distribution
In cumulative frequency with the formula of x/n, what is x?
Added frequency
How do we plot the z-table?
By looking at the first decimal (row) and second decimal (column)
