Unimodal distribution - Study guides, Class notes & Summaries

How to describe a sample Inferential Statistics Bi Modal Central TendencyMultimodal having more than 2 modes Unimodal When distribution only has one mode -the frequencies progressively decline as they move away from the mode. Symmetrical distributions are usually uni modal. bimodal means you have not defined your population if you find a bimodal Mode most frequently occurring measure (value or category) in (distribution) data Mean called location parameter most frequen...

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...

descriptive Statistics computed to reveal characteristics of the sample and to describe study variable How to describe a sample create a frequency distribution of the variable or variable being studied - is a plot of one variable, whereby the x-axis consists of possible values of that variable , and the y - axis is tally of each value Inferential Statistics computed to draw conclusions and make inferences about the greater population, based on the sample data set.
