Data analysis
Calculate and compare the mean, median, mode and range for simple datasets
  • Calculate the mean (x) of a set of data using digital tools

  • Calculate and describe the Loading , Loading , Loading  and Loading 

  • Classify the mean, median and/or mode as Loading  to represent the Loading  or typical value of a dataset

  • Describe and interpret data displays using mean, median and range

  • Identify and describe datasets as having no modes (uniform), one mode (unimodal), 2 modes (bimodal) or multiple modes (multimodal)

  • Identify the range as a Loading  to describe variation in a dataset

  • Compare simple datasets using the mean, median, mode and range

Interpret the effect individual data points have on measures of centre and range
  • Informally identify clusters, gaps and Loading  in datasets and give reasons for their occurrence in the context of the data

  • Identify and explain the impact of adding or removing data values that are clustered at one end of a dataset on the measures of centre

  • Identify and explain the impact of outliers on the measures of centre and range

  • Determine and justify the most appropriate measure of centre to summarise the data in its context

Analyse datasets presented in various ways and draw conclusions
  • Identify and describe the shape and distribution of a dataset using the terms Loading , negatively skewed and positively skewed

  • Define a census as a study of every unit, everyone or everything in a population

  • Define a Loading  as a subset of units in a population selected to represent all units in a population of interest

  • Draw conclusions and make informed decisions about data gathered using data-collection techniques, including census and sampling, which is then presented in Loading , Loading  and charts
