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 louder 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, we first need to arrange the data set in ascending order: $317, 341, 341, 341, 430, 490, 569$. There are an odd number of data points, so the median is the middle value. In this case, the middle value is the 4th data point, which is $341$. Therefore, the median of this data set is $\boxed{341}$.
To find the median of the given data set, we need to arrange the values in ascending order:
317, 341, 341, 341, 430, 490, 569
There are a total of 7 values in the data set. Since 7 is an odd number, the median will be the middle value.
The middle value in this case is the 4th value, which is 341.
Therefore, the median of this data set is 341.
To find the median of a data set, you need to arrange the numbers in ascending order first. Let's rearrange the reaction times in ascending order:
317, 341, 341, 341, 430, 490, 569
Since we have an odd number of data points (7), the median is simply the middle number when the data is arranged in ascending order. In this case, the median is the fourth number:
Median = 341 (ms)
Therefore, the median of this data set is 341 milliseconds.
