The independent variable is that “Data are available for 63 countries‚ with a total sample of 420‚599 individuals. Using a 3-level variance-known model‚ the authors found that individualism was a consistently better predictor than wealth‚ after controlling for measurement‚ sample‚ and temporal variations.” The dependent variables are that individualism is consistently associated with more well-being

Aim To investigate how parachutes work and whether size matters to performance. Background According to Agee (2010)‚ “As a skydiver is falling‚ the force of gravity is pulling them towards the earth… The parachute slows the skydiver down because it causes air resistance or drag. The air pushes the parachute back up‚ and creates a force opposite to the force of gravity‚ slowing the skydiver down.” Question We wanted to find out how the size of a parachute would affect its descent as we felt slowing
