Question

which of the following types of graph can not be interpolated or extrapolated?
pie - chart
line graph
both a and b
none of the above

Explanation:

• Pie - chart: It shows proportions of a whole at a specific point in time. There is no data trend over a continuous variable (like time or quantity) to interpolate (find values within the known data range) or extrapolate (predict values outside the known data range).
• Line graph: It represents data points connected by lines. Since it shows a relationship between two variables (often with one being a continuous variable like time), we can interpolate (e.g., find the value of the dependent variable at a time between two measured times) and extrapolate (e.g., predict the value of the dependent variable for a future time based on the trend).

Answer:

Pie - chart
