[0:00] Statistics helps us collect, organise and make sense of data.
[0:40] A frequency table counts how many times each value or class appears.
[1:25] The mean is the total of all values divided by how many there are.
[2:10] The median is the middle value when data is ordered, and the mode is the most common value.
[2:55] Histograms and frequency polygons let us see the shape of the data at a glance.
