In this second of two lessons, students represent their acquired sleep data using a back-to-back stem-and-leaf plot and draw conclusions based on statistical analysis.
Students conduct a sleep audit over two weeks to test hypotheses regarding improving sleep quality.
Students explore a large data set.
Students calculate the mean, median and mode for sets of data and select the appropriate measure of centre.
This is a colour image of a model of a molecule of hydrogen, H₂. In this model, two hydrogen atoms are represented by grey-white spheres held together by a grey rod that represents a covalent bond.
This is a photograph, possibly taken by John Flynn (1880-1951) and measuring 8.2 cm x 8.2 cm, of an elderly woman seated at a pedal wireless transmitter with three girls behind her. There is no microphone but the woman is operating a morse key. The woman and one of the girls are wearing earphones. The words 'AIM Pedal Transmitter' ...
This is a colour image of a model of a molecule of iodine, I₂. In this model, two iodine atoms are represented by deep red spheres held together by a grey rod that represents a covalent bond.
This is a colour image of a model of a molecule of ethanol, CH₃CH₂OH. In this model, atoms are represented by coloured spheres held together by grey rods that represent covalent bonds. The molecule contains two carbon atoms (the black spheres), one oxygen atom (the red sphere) and six hydrogen atoms (the grey-white spheres).
This is a colour image of a model of a molecule of water, H₂O. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The water molecule contains one oxygen atom (the red sphere) and two hydrogen atoms (the grey-white spheres).
This is a colour image of a model of a molecule of bromine monofluoride, BrF. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The bromine monofluoride molecule contains one bromine atom (the brown sphere) and one fluorine atom (the blue-grey sphere).
This is a colour image of a model of a molecule of oxygen, O₂. In this model, two oxygen atoms are represented by red spheres held together by grey rods that represent a double covalent bond.
