Skills Check List

Probability
- Simple probability and experimental probability - [random numbers generated on calculator]
- Tree diagrams - [covered and videos made in term three]
- Conditional probability - [when the word GIVEN is used]
(reduced sample space - the sample space is all possible outcomes eg: given the person is female....)

The statistical enquiry cycle involves:
- evaluating statistical investigations or probability activities undertaken by others, including data collection methods, choice of measures, and validity of findings
- calculating probabilities, using fractions, percentages, and ratios
- evaluating statistical reports in the media by relating the displays, statistics, processes, and probabilities used to the claims made
- investigating situations that involve elements of chance: calculating probabilities in discrete situations.

When evaluating report look at the following:
- other data that could be collected to improve the analysis
- Improvements to the method of data collection
- better graphs that could be drawn, or other statistics that could be calculated. (If you believe that the best choice of graphs and statistics have been made, explain why)
- whether assumptions/claims made are valid, sensible and accurate
- reliability of the experiment and accuracy of data
- improvements to the question posed (if applicable)

Interpretation of:
- measures of centre (central tendancy: mean, median and mode)
- measures of spread (range, interquartile range, standard deviation)
- statistical graphs and tables (box and whisker, time series, scatter graph, histogram, bar graph etc)

Interpretation of statistical graphs might include a scatter graph!

T-E-X-T is a way to form a paragraph that has structure, making it easy to read.
T for a topic sentence
E for evidence in the form of numbers and calculations
X for eXplain what the numbers mean
T tie up by making a statement that answers the question
