When p <0.05 is reported in a journal that you read for an observed relationship, it means that the author has rejected the null hypothesis. True False

True - A p-value of <0.05 means that there is a 5% chance that the results of the study occurred by chance alone and the research (alternate) hypothesis is true.

coding

Qualitative studies rely on ____________ analysis to discover key themes and patterns. content statistical predictive descriptive

content

Quantitative researchers use data in the form of narrative descriptions. True False

false

The use of the laws of probability to make inferences and draw statistical conclusions about populations based on sample data is referred to as _______________ statistics. sample population inferential descriptive

inferential

The point in a distribution above which and below which 50% of cases fall is known as ___________. standard deviation mean median mode

median - Mode is the most frequently occurring score in a distribution. Mean equals the sums of all scores divided by the total number of scores and a standard deviation is the average deviation of scores in a distribution.

An index of central tendency that indicates the most 'popular' value in a distribution is called ___________. mean range median mode

mode

The difference between the highest and lowest scores in distribution is known as__________. median mean mode range

range

Grounded theory analysis involves the use of a constant comparative method. True False

true

here are four different levels of measurements - from the lowest nominal measurement -> ordinal -> interval to the highest ratio measurement. Match each variable with the level of measurement that captures the highest possible level for that variable.
