![]() ![]() When several samples are taken from a population, the means of these samples scatter around the true mean of the population. Mean error – the standard error of the mean value is output, which is estimated from the random sample. The same applies to the calculation of the variance. (population) – for the standard deviation of population the unbiased estimator is calculated by dividing the sum of squares by (n – 1), while selecting “sample” the sum is divided by n. ![]() 7 is implemented, which is also the default method used by “r”. A review of nine different methods can be found in Hyndman & Fan (1996): “Sample quantiles in statistical packages”. There are various methods to determine the percentile of a distribution of measured values. Accordingly, 25% of all values are greater than the value of the third quartile, that is the 75th percentile. In the right pane of the window you can select typical metrics and values for the descriptive statistics, some of which require further explanation:ġst and 3rd Quartile – The first quartile corresponds to the 25 th percentile and indicates the value below which 25 % of all values fall. (This option is available only if MAXQDA Stats was launched with the data of a MAXQDA project). To generate descriptive statistics for code frequencies per document, switch to the “Codes” tab and select the desired codes. ![]() Select one or multiple variables with the mouse by holding the Ctrl/Cmd key then drag the selection into the right window pane with the mouse, or click the blue arrow in the middle of the window.Drag and drop the variable into the right window pane.The “Office” footswitch has three buttons: Press the left button to rewind 5 seconds, the right button to fast forward 5 seconds.Variables can be selected in several ways:.The black “Science II” switch must be held down to play media data and will stop playing when released.The yellow “Science” switch has the same functionality as the F4 or F5 key (depending on the software setting inside the foot pedal): press once to play, and a second time to stop.Transcribing with a foot pedalįor faster and easier transcription, MAXQDA supports the following foot pedals from Audiotranskription: To resume working on a transcript, right click on the document and select Transcribe audio file or Transcribe video file. You can start and stop Transcription Mode at any time – just close the Multimedia Browser. For detailed explanations on how to use the Multimedia Browser, please refer to the section for coding videos. This makes it possible to highlight and code sections and to set memos and internal links. The whole functionality of the Multimedia Browser is also available. To do this, highlight a text segment, for example, and drag it to a code in the “Code System”. You can code the typed text with new or existing codes during transcription. ![]()
