Dissecting Scope Components

  • Major parts of a dissecting scope include the base, arm, stage, and ocular lenses.

Independent Variable

  • Refers to factors that a scientist manipulates during an experiment, such as exercise and diet.

Dependent Variable

  • The aspect being measured to see if it changes in response to independent variables, e.g., blood cholesterol levels.

Statistical Measures

  • Mean: Average value calculated by summing all numbers and dividing by their count.
  • Median: The middle value in a sorted list of numbers.
  • Mode: The most frequently occurring value in a dataset.
  • Range: Difference between the highest and lowest values in a set.

Organic Molecule Testing Solutions

  • Solutions used include water, glucose, sucrose, starch, onion juice, and an unknown solution.
