*WILL MARK BRAINLIEST*
Mrs Smith's class took a test on solving quadratics. After she graded the tests, she calculated the following statistics for them. Below is what she calculated:
Lowest score: 53 First Quartile: 63 Mean: 74
Median: 75 Third Quartile: 82 Standard Deviation: 13.2
Highest Score: 95
If she realized she made a mistake on the lowest score and the students' grade increased by 5 points, pick how this will effect the statistics:
Median (does it stay the same, increase or decrease?)
Interquartile Range (does it stay the same, increase or decrease?)
Mean: (does it stay the same, increase or decrease?)
Standard Deviation: (does it stay the same, increase or decrease?)
