Today we're going to start our two-part unit on data visualization. Up to this point we've discussed raw data - which are just numbers - but usually it's much more useful to represent this information with charts and graphs. There are...

Pupil outcome: I can construct pictograms from data. Key learning points: - Data presented as a list can be represented as a pictogram - Data presented in a table can be represented as a pictogram - The icons chosen should not be...

Pupil outcome: I can compare and contrast the usefulness of the different representations when calculating theoretical probabilities. Key learning points: - The probability of an outcome can be calculated from each representation. -...

Pupil outcome: I can construct a cumulative frequency graph. Key learning points: - A cumulative frequency graph can be drawn from a frequency table - It can be easier to create another column to sum the frequencies - Cumulative...

Pupil outcome: I can construct a table from a histogram. Key learning points: - A frequency table can be used to construct a histogram - A histogram can be used to construct a frequency table - Data is sometimes collected using uneven...

Pupil outcome: I can estimate the mean and median from a histogram. Key learning points: - The mean can be found using a histogram - The median can be found using a histogram - An estimate for the frequency within a given data range can...

Pupil outcome: I can calculate the mean from a grouped frequency table. Key learning points: - The mean is a measure of central tendency. - The mean can only be estimated with a grouped frequency table. - Calculating this from a grouped...

Pupil outcome: I can use the fx-991CW to perform calculations with data. Key learning points: - Some calculators can perform more than just basic calculations. - The fx-991CW can produce a statistical summary of a set of data. - The...

Pupil outcome: I can construct bar charts from data. Key learning points: - Data presented as a list can be represented as a bar chart - Data presented in a table can be represented as a bar chart - The type of data determines how the...

Pupil outcome: I can use my understanding of sampling to solve problems. Key learning points: - Samples can be evaluated to determine the validity of any conclusions. - A suitable sample size can vary, depending on the statistical...

Pupil outcome: I can use measures of central tendency and spread to compare two data sets in context. Key learning points: - Data can be hard to compare when presented in lists and tables. - Statistical summaries can be calculated to...

Pupil outcome: I can construct/interpret bar charts and pictograms. Key learning points: - Certain data is suitable for a pictogram or bar chart. - The shape of the graph can be estimated from the data. - For larger data sets, technology...

Pupil outcome: I can use my understanding of sampling to solve problems. Key learning points: - Samples can be evaluated to determine the validity of any conclusions. - A suitable sample size can vary, depending on the statistical...

Pupil outcome: I can understand what the range is measuring, how it is measuring it and calculate the range from data presented in a range of different ways. Key learning points: - The range is a measure of spread. - The range is...

Pupil outcome: I can calculate the median, mode and range from a grouped frequency table. Key learning points: - The median and mode are measures of central tendency. - The range is a measure of the spread of the data. - Calculating...

Pupil outcome: I can calculate the mode from data presented in a frequency table and different graphs. Key learning points: - The mode can be calculated from an ungrouped frequency table. - The mode can be calculated from a bar chart. -...

Pupil outcome: I can use measures of central tendency and spread to compare two data sets in context. Key learning points: - Data can be hard to compare when presented in differing formats. - Being able to convert/interpret differing...

Pupil outcome: I can calculate probabilities from tables and two-way tables. Key learning points: - The probability of an outcome can be found by considering a table - The probability of an event can be found by considering a table...

Pupil outcome: I can calculate the mean, median, mode and range from a frequency table. Key learning points: - The mean, median and mode are measures of central tendency. - The range is a measure of the spread of the data. - Calculating...

Pupil outcome: I can construct pie charts from data. Key learning points: - Data presented as a list can be represented as a pie chart. - Data presented in a table can be represented as a pie chart. - A larger data set requires...

Pupil outcome: I can calculate a conditional probability from a Venn diagram. Key learning points: - A Venn diagram can be used to calculate conditional probabilities - A Venn diagram can be used to calculate conditional probabilities...

Pupil outcome: I can calculate the median from data presented in a frequency table and different graphs. Key learning points: - The median can be calculated from a line graph. - The median can be calculated from an ungrouped frequency...
