Homework: Section 1.2 Homework Score: 0 of 1 pt 10 of 10 (9 complete) 1.2.30 The temperatures (in C) of water samples taken simultaneously in a large lake are shown below. 23.5 273 24.6 27.9 227 23.4 Determine whether the data are qualitative or quantitative and identify the data set's level of measurement. Are the data qualitative or quantitative? Qualitative Quantitative What is the data set's level of measurement? O O Ordinal Ratio Interval O Nominal

Answer 1

1. It is Quantitative data. Quantitative data involves some numerical values and can be counted or measured. Here, data is quantitative because it has some numerical values like 23 degree, 27 degree etc.

2. Option (c) is correct

Data is interval data, because interval data has some numerical values with difference between the values is standardized or meaningful and there is arbitrary zero. Temperature can be below zero also.

Option (a) is incorrect as in ordinal data, rankings or orders or scalings are done.

Option (b) is incorrect as in ratio data, similar to interval data, it has some numerical values with difference between the values is standardized and meaningful but with true or absolute zero value and no negative values.

Option (d) is incorrect as nominal data is the data that can be separated into categories.
