A researcher was interested in determining if the attitude of statistics’ students changed from the beginning to the end of the course. She asked her students to fill out an “Attitudes Toward Statistics” scale at the beginning and end of the course.   State the alternative hypothesis. Is this directional or non-directional test? IV (levels, b/w or w/I)? DV (scale of msmt)? Type of test?

what would happen to the mean, median, and mode values that you calculated ,if you added one player to the team whose points per game for the season was 25.  just tell me if the mean, median, and mode would go up, down, or stay the same. Give an example of variable for which  the mean would not be appropriate to describe the data (that is, tell me a circumstance in which you would not want to use the mean to describe a dataset)

when computing descriptive statistics, we are interested only both describing our data and also in presenting the means and standard deviations of all dependent variables. True or false When writing your participant section, you include all measures of central tendency (mean, median, mode) and all measures of variablility (variance, range, standard deviation). True or false

Are written conclusions a form of statistics?
