Answer the following question given this paragraph: Many samples have a lot of variation in measurements. Variation can be described with a statistic called the range. The range is the total spread of values in a sample. It is calculated by subtracting the smallest value from the largest value. Q: What term is used to describe the total spread of values in a sample? Choices: - variety - axis - scale - range A:
**Answer**
range
Q: Answer the following question given this paragraph: The second equation is equivalent to the first. Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since PE = qV . The car battery can move more charge than the motorcycle battery, although both are 12 V batteries. Q: What term is not the same as energy, but means the energy per unit charge? Choices: - frequency - speed - mass - voltage A:
A: voltage
