Final answer:
In the pie model for causality, an entire piece is referred to as a 'slice'. This term is used in the context of pie charts, where each slice represents a proportion of the total.
Step-by-step explanation:
An entire piece in the pie model for causality is referred to as a slice. This model is commonly used in visual representations like pie graphs or pie charts, where the entire circle represents a whole and the slices indicate parts or segments of the whole. When we divide a pie into equal pieces, each piece is known as a slice, which represents a share of the total, such as a percentage or fraction of the overall quantity.
Understanding the concept of pie slices can be helpful in various applications, for example, when dividing a population into age groups or analyzing government spending across different categories. Pie graphs provide a visual representation that helps to easily compare relative sizes of the parts to the whole. A slice of pie in a pie chart helps in quickly grasping the portion that a segment represents within the total context.
