On each trial of an experiment a participant is presented with a constant soft noise which is interrupted at some unpredictable time by a slightly louder sound the time it takes for the participant to react to the latter sound is recorded the following list contains the reaction times in milliseconds for seven trials of this experiment 341 569 341 490 341 430 317 what is the median of this data set if your answer is not an integer round your answer to one decimal place
To find the median of a data set, you first need to arrange the numbers in ascending order:
317, 341, 341, 341, 430, 490, 569
Since there are an odd number of numbers (7), the median is the middle number. In this case, the middle number is 341, so the median is 341.
Did you round your answer to the nearest decimal place
Apologies for not rounding the answer to the nearest decimal place.
Since the median is 341, which is already an integer, there is no need for rounding.
What is the mean of this data set if your answer is not an integer round your answer to the one decimal place
To find the mean of a data set, you need to sum up all the values and then divide by the total number of values.
Sum: 317 + 341 + 341 + 341 + 430 + 490 + 569 = 2829
Total number of values: 7
Mean = Sum / Total number of values
Mean = 2829 / 7 = 404.1 (rounded to one decimal place)
So, the mean of this data set is 404.1.
How many modes does the data set have and what are their values
A zero modes B one mode or see two modes
To determine the modes of a data set, you need to identify the values that appear most frequently. In this case, the data set is:
317, 341, 341, 341, 430, 490, 569
It is clear that the value "341" appears three times, which is more frequently than any other value in the data set. Therefore, the data set has one mode, with a value of 341.
