Place the rule directly on the surface being measured, rather than at a distance from it.
You should position your eye directly in line with the scale or mark you are reading to avoid parallax error. This ensures that you are looking at the measurement or reading from a straight-on perspective, reducing any angle-induced errors.
To measure meter accurately in a scientific experiment, use a ruler or measuring tape with clear markings in millimeters. Ensure the object being measured is straight and aligned with the measuring tool. Take the measurement at eye level to avoid parallax error. Record the measurement to the nearest millimeter for precision.
The strip of mirror is mounted to help eliminate parallax errors when reading the value on the scale of the voltmeter. By aligning the needle's reflection with its actual position on the scale in the mirror, the observer can avoid viewing the needle from an angle, which could result in an inaccurate reading due to parallax. This setup ensures a more precise and accurate reading of the voltmeter.
Parallax error should be avoided during titration experiments because it can lead to inaccurate volume readings. Parallax error occurs when the observer's eye is not directly in line with the measurement markings, causing a shift in perceived position. This can result in incorrect volume measurements and affect the precision and accuracy of the titration results.
To read a mercury thermometer accurately, hold it at eye level and make sure the mercury level is below your body temperature. Wait for a few minutes for the mercury to stabilize, then read the temperature at the point where the mercury stops. Be sure to note the temperature in whole numbers and avoid parallax errors by looking straight at the thermometer.
Ensure that the measuring cylinder is on a flat surface to get an accurate measurement. Also, read the measurement at eye level to avoid parallax errors. Handle the measuring cylinder carefully to prevent breakage.
When measuring the length of an object with a ruler, ensure that the ruler is aligned straight along the object's edge for an accurate reading. Start measuring from the zero mark of the ruler, as misplacing the starting point can lead to incorrect measurements. Additionally, make sure to read the measurement at eye level to avoid parallax error, which can distort the reading.
There is no such way to avoid parallax error, you just have to be careful.. :)

When a readng is taken from an analog meter, the pinter must be viewed correctly as it is a short distance away from the scale, so if read from one side, an error of several divisions will occur. To avoid this error the meter should be read from a position directly above the pointer. To help avoid this error most meters have a mirror in the scale so that the error may be dicerned more readily.
When measuring volume in a graduated cylinder, you should read the level at the bottom of the meniscus, which is the curved surface of the liquid. Make sure your eye is level with the meniscus to avoid parallax error. The measurement should be taken at the lowest point of the curve for an accurate reading.
That's great I have learned something new

Use a graduated cylinder or beaker with clear markings for accurate measurement. Read the volume at eye level to avoid parallax errors. Measure at the bottom of the meniscus, the curved surface of the liquid. Ensure the container and liquid are at room temperature for accurate readings. Keep the container steady on a flat surface to prevent spills and ensure precision.
Following are some precautions to be taken while measuring length with the help of a metre scale: Scale must be placed in contact with the object along its length. Eyes must be exactly perpendicular to the point where the measurement is to be taken, to avoid parallax error. If the ends of a scale are broken/damaged we should avoid taking measurements from the end. Instead, we should place the object on any other fully visible mark on the scale (say, on 2 cm instead of 0). Then you must subtract the reading on this mark from the reading at the other end.
