Statistics and Probability

Making Sense of Data

Statistics and probability help you interpret data and predict chances. On the ACT, you'll analyze charts, calculate averages, and determine probabilities.

Key Topics

  • Mean, Median, and Mode: Measures of central tendency.
  • Probability: Likelihood of an event, from 0 (impossible) to 1 (certain).
  • Data Interpretation: Reading graphs, tables, and charts.
  • Range and Standard Deviation: Measuring data spread (standard deviation is rarely tested, but useful to know).

Real-World Use

These skills let you understand sports stats, election polls, or the odds of winning a game.

Tips

  • Add up all data points and divide to find the mean.
  • Use probability formulas to calculate possible outcomes.

Examples

  • Finding the average score of a soccer team over a season.

  • Calculating the probability of drawing a red card from a shuffled deck.

In a Nutshell

Statistics and probability let you make sense of data and chance.
