## Unit 10 Data Analysis and Probability.

Experimental probability is frequently used in research and experiments of social sciences, behavioral sciences, economics and medicine. In cases where the theoretical probability cannot be calculated, we need to rely on experimental probability. For example, to find out how effective a given cure for a pathogen in mice is, we simply take a number of mice with the pathogen and inject our cure.

Experimental probability, also known as Empirical probability, is based on actual experiments and adequate recordings of the happening of events. To determine the occurrence of any event, a series of actual experiments are conducted. Experiments which do not have a fixed result are known as random experiments. The outcome of such experiments is uncertain. Random experiments are repeated.

Help children begin to collect and compare data with this Bar Graph Template.There are many reasons for us to use a blank graph template - we can use them as an interesting way to teach students or ask your class to tally and compare data.Our blank bar graph template is perfect for use in your primary school classroom as it gives students a visual display to compare quantities and categories.

In order to determine the probability represented by the shaded area of the graph, use the standard normal Z-table provided at the bottom of the page. Note that there are different types of standard normal Z-tables. The table below provides the probability that a statistic is between 0 and Z, where 0 is the mean in the standard normal distribution. There are also Z-tables that provide the.

The probability of getting a particular number of heads is shown in a table (alongside the cumulative probability) and in a bar chart. The second interactive sheet deals with a similar experiment when 20 coins are tossed. There are three more sheets of questions which may be suitable for use in the classroom. Probability: Relative Frequency.

Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes. As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.
