Graphical Representation Flashcards
What is a frequency table?
A table that shows the rate of occurrence for a number of measured values
What is a line graph?
A diagram that shows a linear representation of frequencies of data, where scores are plotted and joined one by one with straight lines
What is a bar chart?
A diagram that represents frequencies of non-continuous (discrete) data, where there should be gaps between all bars and a gap between the first bar and y-axis
What is a pie chart?
A diagram that represents data proportionately as part of a whole picture of responses, which needs a key to explain segment labelling
What is a histogram?
A diagram that represents the distribution of frequencies for continuous data, where no gaps should be present between bars
What is a scatter diagram?
A diagram that represents a relationship/correlation between two or more co-variables, which does not need to include a line of best fit
What are distribution curves?
Linear representations of data that include a mean, median, and modal score to show the spread of data
What is positive skew?
A type of skewed distribution, where the mode is less than the mean
What is negative skew?
A type of skewed distribution, where the mode is greater than the mean
What is a normal distribution?
A type of distribution where the mean, median, and mode are equal
