Question

1.Create a frequency table with a column for relative frequency for the following data. 2.Draw a scatter plot that has strong positive correlation (4,4,4,5,5,5,5,5,6,6,6,6,6,6)

Answer 1

Answer 1

The data is:

Data
4
4
4
5
5
5
5
5
6
6
6
6
6
6

The frequency table is:

Number	Frequency	Relative Frequency(in %)	Relative Frequency(in decimal)
4	3	21.43%	0.214285714
5	5	35.71%	0.357142857
6	6	42.86%	0.428571429
Total	14	100%	1

Answer 2

Consider the dummy data:

X	Y
1	10
2	22
3	30
4	35
5	49
6	60
7	70
8	77
9	89

Scatter plot with strong positive correlation:

Correlation = r = 0.99742
