BASICS OF RESEARCH & DATA
This type of sampling is exemplified by taking a handful of jellybeans from a bowl to use as your sample.
What is simple random sampling?
This is the graph most often used for representing quantitative variables visually.
What is a histogram?
This measure of variation is equal to the maximum value minus the minimum value.
What is the range?
We use this part of the distribution to determine the direction of its skewness.
What is the tail of the distribution?
These are the two views available to us on SPSS.
What are "Variable View" and "Data View"?
What is a primary source?
This is the first step when conducting any analysis using SPSS.
What is "FREQUENCIES"?
What is the mode?
The whiskers of a box plot represent these values of a distribution.
What are the minimum and maximum values?
This section of a frequency table on SPSS includes the percentage of each case barring any missing data.
What is the 'Valid Percent' section?
We cannot get measures of central tendency or variation from this type of variable.
What is a categorical variable?
We use this command to get a better sense of how certain variables interact without permanently altering the dataset.
What is the "TEMPORARY" command?
This measure of variation is the difference between the upper and lower quartiles.
What is the inter-quartile range?
If the confidence in this statistical measure is high, than precision of that estimate is low. And vice-versa.
What is a confidence interval?
This type of variable is sometimes called a 'signal/no signal variable'.
What is a binary coded variable?
The median represents the 50th of this statistic.
What are percentiles?
These commands allow us to manipulate our data to best suit our research interests.
What are the "IF" and "RECODE" commands?
This measure of variation is the average distance between an observation and the mean score.
What is standard deviation?
When interpreting a histogram, we first talk about this.
What is the shape of the distribution?
This SPSS command allows us to circumvent the need for a table for a quantitave variable with many different scores.
What is "FORMAT=NOTABLE"?
This way to visualize data includes photos, graphs, drawings, and diagrams.
What are figures?
This visual representation of data is used to compare how various groups perform in a given variable.
What is a box-plot?
We typically use this measure in cases with a large number of outliers, or with extreme outliers.
What is the median?
When reporting any values in a table, it should follow this format.
What is APA?
With a confidence interval of 95%, this would be our Z score.
What is 1.96?
