7. the data shown in the table were collected during an evaporation experiment. which statement best describes the data collected? day 1 2 3 4 5 6 7 water depth (inches) 18 17.5 16.25 14 10.6 8.7 5.3 a there are 7 observations and 1 attribute. the attribute was likely measured using a measuring cup. b there are 7 observations and 1 attribute. the attribute was likely measured using a ruler. c there is 1 observation and 7 attributes. the attributes were likely measured using a measuring cup. d there is 1 observation and 7 attributes. the attributes were likely measured using a ruler.

Answer

Brief Explanations:

Each row in the table represents an observation (7 days of data collection). The water - depth is the single attribute being measured. Since water - depth is a linear measurement of length, it is likely measured using a ruler.

Answer:

B. There are 7 observations and 1 attribute. The attribute was likely measured using a ruler.
