You will need to choose LOG10 from the list of operators in the box andĪre writing this equation, do NOT put in an equal sign - this is not We will use the transformation y = log 10( x +1). The arrows, move the mantle data into the equation editor box. What do you notice? (Don't worry about the detrended Compare this plot to the Q-Q plots in the Go to Graphs, Q-Q plot, and choose the mantle length data. Also note the "stretch and squish" evident in the plot of the Note how the shapes of the graphs changeĭepending on what values are on which axes. Simple, and choose your x and y variables. This data normally distributed? left skewed? right skewed? Play with them until you get a histogram thatĬolumn of data you'd like to graph, specifically the mantle lengths (raw SPSS should keep track of, particularly for the Z-scores. "numeric" - and you may want to increase the number of decimal places Also, column names can be a maximum of 8Ĭolumns, you should make sure that they are the right data type - in this case they should be It is not case sensitive, so everything willĪppear in lower case, and it doesn't like symbols or spaces. SPSS has a bunch of rules about what you can name your columns. Name yourĭouble-clicking on the top of the column. The actual mantle lengths and the normal scores and Z-scores. Programs, SPSS 8.0 for Windows (Student Version). They are not meant to be insulting! They are just to take into account the many different levels of computer For example, if you just wanted to select cases in which your variable 'v1' contained the values of '1,' '2,' or '3,' your Expression box should look something like, 'ANY(v1,1,2,3).May seem super-simplistic to some of you. ![]() If you have more than two values, you can specify those values by specifying a comma after each value. ![]() You would click on the 'ANY' function in the function box within the 'If condition is satisfied' box within Select cases and replace the first question mark with your variable name and then replace the next two question marks with your two values. For example, if your variable were called 'v1' and you wanted to select cases for which 'v1'='1' and 'v1' = '2,' your Expression box within Select Cases should indicate, 'v1=1 OR v1=2.' The 'ANY' function also accomplishes the same result. If you would like to specify a condition for just one variable in which you want to select cases based on two or more values within that variable, you need to use the 'OR' function or use the 'ANY' function. The 'AND' function in the Select Cases within SPSS is used to specify a condition for 2 or more separate variables. ![]()
