C.11 interpret graphed data PART 2 evaluate changes in level, trend & variability
HINT ***
A straight line representing the trend is called the trend line or line of progress
a high, stable level of responding followed by a low stable level of responding in the same phase
Which best describes the graph? A) a high, stable level of responding in the first phase followed by a low stable level of responding in the second phase B) a moderate variable level of responding C) a high, stable level of responding followed by a low stable level of responding in the same phase
indicated with a horizontal line
average level is A) indicated with a horizontal line B) the mean of the values of the IV C) the sum of the values of the dependent variable
mean of the values of the DV
average level is the A) sum of the values of the DV B) mean number of the days of the condition C) mean of the values of the DV
is the central tendency of the data along the vertical axis
level A) refers to the magnitude of the data on the vertical axis averaged across conditions B) is the central tendency of the data along the vertical axis C) refers to the direction of the data path D) is a measure of variability
HINT ****
the average level is the arithmetic mean of the values of the DV it is the sum of the values of the DV divided by the number of values level is indicated with a horizontal line
HINT
the average level is the arithmetic mean of the values of the DV. it is the sum of the values of the DV divided by the number of values level is indicated with a horizontal line
direction of data path
trend is the A) direction of data path B) magnitude of the data on the vertical axis C) magnitude of the variability
line of progress
trend line is the A) line of progress B) curve of the data path C) magnitude of the data on the vertical axis
HINT*
variability (it is stable if few ups and downs)
high stable responding followed by a decreasing trend in the second phase
which best describes the graph A) high stable responding followed by a decreasing trend in the second phase B) low, variable responding followed by low, stable responding in the same phase C) high, variable responding followed by low, stable responding in the same phase
high, variable responding followed by low, stable responding in the same phase
which best describes the graph? A) high, stable responding followed by decreasing trend in the second phase B) high, stable responding followed by low, stable responding in the same phase C) high, variable responding followed by low, stable responding in the same phase
low, variable responding followed by low, stable responding in the same phase
which best describes the graph? A) low, variable responding followed by low, variable responding in the same phase B) high, stable responding followed by decreasing trend in the second phase C) low, variable responding followed by low, stable responding in the same phase
