Hello, I am working on the homework for statistics class, and I am not sure how to answer the questions below:

1. Lieberman et al. (1999) measured aggression with the Hot Sause Allocation task. Participants get hot sauce and are told to decide how much hot sauce someone else should eat. The amount of hot sauce is measured in grams. Is the scale of measurement for the amount of hot sauce nominal, ordinal, or interval/ratio?

2. In addition to these behavioral measures (number of pins and grams of hot sauce), aggression is also measured using paper and pencil measures. One such measure is the Aggression Questionnaire (Bus & Perry, 1992). One section of this questionnaire assesses Physical Aggression with nine different questions (e.g., If somebody hits me, I hit back; I get into fights a little more than the average person). Participants respond to each of the nine questions on a 5-point scale where 1 = extremely uncharacteristic of me and 5 = extremely characteristic of me. This 5-point scale is an example of a ____________ scale of measurement. (nominal, ordinal, or interval/ratio).

3. Researchers do not typically analyze just one question. Instead, they sum a participant's responses to all nine questions; therefore, an individual's score on the entire nine-question aggression scale could range between a low of 9 to a high of 45. Although each item on the questionnaire is measured on an ordinal scale, when researchers sum individual items intended to measure the same thing (e.g., physical aggression) the resulting value is commonly treated as a more precise scale of measurement (e.g., Carifio & Perla, 2007). This would be a __________ scale of measurement. (nominal, ordinal, or interval/ratio)
