histogram correct answers the most basic way of visualising data. shows the frequency and counts of data and can tell us about how scores on a variable are distributed. what is binning (histograms) correct answers binning are the values of the x-axis that are put into 'bins' at predetermined non-overlapping intervals. They help to better reveal the distribution of scores as x-axis values are either inidivudal values or can be bent by binning. basically the coloums that are found in historgr...
