(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)
Probability provides the mathematical framework for quantifying the likelihood of events. Vjerojatnost i statistika
1.2 - The 7 Step Process of Statistical Hypothesis Testing | STAT 502 : Uses sample data to make predictions about a whole group
: Meteorologists combine historical data and probabilistic models to predict the chance of rain or storms. median (middle value)
: 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).
: 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).
: Researchers use statistics to determine if a new medical treatment is more effective than a placebo.
