GRAPHS

Types of Graphs PIE CHART • compare parts to the whole (proportions or percentages) • use for nominal (categorical /qualitative) variable data conclusion of dependent What is independent control of this arethe three controlled this experiment? variable of(constants) this experiment? variables of this experiment? selling Did Apple’s computer quarter and 3 sales Year being sold? Country Apple’s average sales in smart in increase products, orsold? or Location being US 2015 forphone quarter 3 from 2014 sold decrease in compared United States, to last Type ofthe Apple computer (or average Apple sales during year? quarter 3 products and phone fromsmart a Europe Q 3 2015 or a being sold? Q 3 2015 competitor This type of graph is used for what levels of data? ordinal categoric al nominal

Types of Graphs BAR GRAPH • compare groups • nominal on X (IV) & numbers (quantitative) on Y (DV) may have gaps independent What is dependent arethe three What is the conclusion control of variable of this controlled variables this of this experiment? (constants) of this experiment? testing potato enzymes, no treatment or the 5 minutes of reaction normal treatment time, room temperature the treatment decreased (22°C) the enzyme activity This type of graph is used for what levels of data? ordinal categoric al nominal

Types of Graphs HISTOGRA M • distribution of a continuous data set that has been divided into equal class intervals values) • (ranges numbersof(quantitative) on both X (IV) & Y (frequency) dependent Petal Length vs. Frequency.

Types of Graphs LINE GRAPH • compare change over time • numbers (quantitative) on both X (time)What & Y (DV) is the control What are three • line may connect data points conclusion of this independent of this experiment? dependent variable controlled variables experiment? variable of this experiment? (constants) of this experiment? Has the current experiment? year’s monthly Monthly averages Location is Turku, average for the last 10 or temperatures 100 years at noon, measured increased measured in full compared to a direct sunlight baseline of the last This type ofyears? graph is 10 or 100 used for what levels of data? ratio quantitati interv ve

Types of Graphs SCATTER PLOT • correlation of variables • • numbers (quantitative) bothnot X (IV) & Y (DV) best fit line or trend lineon (does connect data points) What is dependent independent arethe three What is the conclusion control of variables this controlled this of this experiment?
