: Researchers use statistics to determine if a new medical treatment is more effective than a placebo.

: Focuses on summarizing data using visual tools like histograms or numerical measures such as mean (average), median (middle value), and standard deviation (how spread out the data is). Vjerojatnost i statistika

(Probability and Statistics) is a foundational mathematical discipline focused on understanding uncertainty and making sense of data. While related, they approach problems from opposite directions: probability uses a known model to predict future outcomes, while statistics uses observed data to build or verify a model. 1. Probability (Vjerojatnost) : Researchers use statistics to determine if a

: It involves defining a sample space (all possible outcomes) and events (subsets of those outcomes). Key formulas include the Law of Total Probability and Bayes' Formula , which helps update the likelihood of a hypothesis as new evidence appears. Key formulas include the Law of Total Probability

: Meteorologists combine historical data and probabilistic models to predict the chance of rain or storms.

: These are the "backbone" of the field, representing numerical values assigned to outcomes of random processes. They can be discrete (countable, like a coin flip) or continuous (measurable, like temperature).

: Uses sample data to make predictions about a whole group. This includes Hypothesis Testing (using a 7-step process to see if a claim holds up) and Confidence Intervals (estimating a range where a true value likely falls).
