Answer: Cold length 7+days and medicine taken is 0.24, the box under is 0.76. Cold length 7+days and medicine not taken is 0.69 and the box under is 0.31. It should look like: 0.24 0.69
0.76. 0.31
Step-by-step explanation: the box is vertical, the total is on the bottom and not the side. This means that you would have to add 6 and 19 together to get 25. 6/25 is 0.24 and the box under would be the rest of the number to get to 1.00 (0.76) because the total is on the bottom. If the total was on the side then you would do 6+27=33, then 6/33 = 0.18 and the remaining amount needed to get to 1.00 is 0.82. Furthermore, if the table has the total at the bottom then, the numbers you add are on the bottom and top box. If the table has the total on the side then, the numbers you add are the boxes that are on the left and right. Remember to round to the nearest hundredth. Your welcome.
The two-way column relative frequency table is,
Medicine taken Medicine not taken
cold length (≥ 7 days) 0.24 0.69
cold length (< 7 days) 10.76 0.31
Total 1.00 1.00
What is two-way frequency table?
- "It is a way to display frequencies for two categorical variables."
- "One category is represented by rows and a second category is represented by columns."
What is two-way relative frequency table?
"It is a way to display relative frequencies (percentages or ratios), instead of just frequency counts."
For given example,
we have been given a two-way frequency table on whether medicine was taken and cold length.
We need to find the column relative frequency table.
First we find the total of each column.
Medicine taken Medicine not taken
cold length (≥ 7 days) 6 27
cold length (< 7 days) 19 12
Total 25 39
Now, divide each element of column by its respective total.
Medicine taken Medicine not taken
cold length (≥ 7 days) 6/25 27/39
cold length (< 7 days) 19/25 12/39
Total 25/25 39/39
Therefore, the two-way column relative frequency table would be,
Medicine taken Medicine not taken
cold length (≥ 7 days) 0.24 0.69
cold length (< 7 days) 10.76 0.31
Total 1.00 1.00
